jQuery form plugin - uploading file to a different domain - asp.net

I have a asp.net website which is supposed to upload files to a handler from a different application / domain. I'm using jQuery Form plugin. When trying to make an example on the same domain (uploading to the same domain) this setup works with success. When trying to upload file with from siteA to siteB I see in firebug that response from handler has been returned (in the Network tab) and is valid, however, the code never enters the 'success' handler, instead giving me such errors in the firebug console:
[jquery.form] Server abort: Error: Permission denied to access property 'document' (Error) log:
[jquery.form] cannot access response document: Error: Permission denied to access property 'document'
[jquery.form] aborting upload... aborted
In chrome it is:
Unsafe JavaScript attempt to access frame with URL http://domainB/handler.ashx from frame with URL domainA. Domains, protocols and ports must match.
Now, I am aware of the fact that there are some policies about ajax calls between domains, but it seems that jquery form plugin simply tries to access some url that is forbidden.
Does anyone have a workaround for it? Any solution please!:)
UPDATE:
I ended up hacking jquery.form so it doesn't throw cross-site exception and since I don't need actual result of upload - it works for me!

Check this and yes, this is a same-origin policy. There are ways to work this around using flash, iframes, jsonp etc but this will require editing a plugin.

Firefox refuses to load firebase auth script

When trying to use Firebase Authentication with Google, the error auth/internal occurs and the following warning appears in the console:
<script> source URI is not allowed in this document: “https://apis.google.com/js/api.js”
This only happens in Firefox. How can I avoid it?
Firefox has a different policy for how network requests are treated within your script.
Firefox requests occur only within the context of the extension.
You need to declare which sites you are making requests to
You will have to place these within
manifest.json
in the permissions key

Microsoft application - Redirect URI allows 'localhost' but not '127.0.0.1'

I have developed an application that allows MSA (Microsoft Account) authentication. I have registered my app here: https://apps.dev.microsoft.com.
When testing my app locally, I can access my app with no problem at my SSL URL of https://localhost:44300, and MSA works fine. When I registered my app, I used https://localhost:44300/signin-microsoft as the Redirect URI.
Problem: I can also access my app at https://127.0.0.1:44300, as one would expect. However, MSA here doesn't work. The error page says, We're unable to complete your request.
Microsoft account is experiencing technical problems. Please try again later. And the URL of the error page reveals that the error is with a mismatch in the Redirect URI: https://login.live.com/err.srf?lc=1033#error=invalid_request&error_description=The+provided+value+for+the+input+parameter+'redirect_uri'+is+not+valid.+The+expected+value+is+'https://login.live.com/oauth20_desktop.srf'+or+a+URL+which+matches+the+redirect+URI+registered+for+this+client+application.
In the Microsoft Apps page, when I try to update the Redirect URI from https://localhost:44300/signin-microsoft to https://127.0.0.1:44300/signin-microsoft, it doesn't allow me to save my change and it shows me this error: Your URL can't contain a query string or invalid special characters, and it provides a 'Learn More' link: https://learn.microsoft.com/en-us/azure/active-directory/active-directory-v2-limitations#restrictions-on-redirect-uris
After reading the info in this link, I see nowhere that a URI like mine (https://127.0.0.1:44300/signin-microsoft) would be an unacceptable URL, as I'm not breaking any of their rules: I have no invalid characters, no query strings, etc.
My research: Looking online, people are getting the Your URL can't contain a query string or invalid special characters because they are actually using a query string or invalid special characters, such as in this link: https://social.msdn.microsoft.com/Forums/en-US/4f638860-ea57-4f0e-85e0-b28e1e357fe2/office-365-app-authorization-redirect-uri-issue?forum=WindowsAzureAD. I couldn't find a case where someone has entered a valid URI and they weren't allowed to save it.
Why I need 127.0.0.1 to work: I need to expose this website, which is running on my local box. In order to have the website running without having an instance of Visual Studio opened all the time, I'm using csrun to host my website in Azure local fabric (by the way, my app is an Azure Cloud Service, with a ASP.NET MVC 5 app as a web role). I followed this instruction for csrun: http://www.bardev.com/2013/03/12/how-to-deploy-application-to-windows-azure-compute-emulator-with-csrun/. Using csrun, it allowed me to host my website in https://127.0.0.1:444 (but, as with https://127.0.0.1:44300, MSA doesn't work). My end goal is to expose this website with a public URL using ngrok (https://www.sitepoint.com/use-ngrok-test-local-site/), so that anyone can access my site.
Therefore, my main question is: how can I have the Redirect URI be https://127.0.0.1:44300/signin-microsoft instead of https://localhost:44300/signin-microsoft?
Make sure you access this portal through https://identity.microsoft.com as this is the only way the steps below will work.
You can get around this error right now by adding the reply URL through the manifest. Login to the portal, select the app you want to configure, and scroll down and hit the Edit Application Manifest button. Then you can add your https://127.0.0.1:44300/ to the replyUrls field.
There's some funny behavior that will only allow this right now if you only register other localhost reply Urls. If this is the only reply URL you need then it shouldn't be a problem.

arcanist install-certificate fails

I set up my own hosted phabricator, everything is working fine (Diffusion repo etc)
I ran into problem after I installed arcanist on my dev box and run 'arc install-certificate', got exception as following:
rying to connect to server...
LOGIN TO PHABRICATOR
Open this page in your browser and login to Phabricator if necessary:
http:///conduit/login/
Then paste the API Token on that page below.
Paste API Token from that page: cli-e644viducdcccrge4i7zo5nfa66d
Usage Exception: The token "cli-e644viducdcccrge4i7zo5nfa66d" is not a valid API Token. The server returned this response when trying to use it as a token: ERR-CONDUIT-CORE: Attempting to access attached data on PhabricatorUser (via getAwayUntil()), but the data is not actually attached. Before accessing attachable data on an object, you must load and attach it.
I am wondering what's might go wrong? Thank you very much for your insights!
I've seen this problem occur many times with our users. In every case so far, the problem has been that users have set up the phabricator uri incorrectly.
Suggestion:
Check your project .arcconfig or your global .arcrc files (if you're doing this outside a project).
Verify that the URI to your Phabricator site is correct. The typical issue I've seen is accessing using http:// rather than https://

What does "pending" mean for request in Chrome Developer Window?

What does "Pending" mean under the status column in the "Network" tab of Google Chrome Developer window?
This happens when my page script issues a GET request whose response contains content-headers for downloading a CSV file:
Content-type: text/csv;
Content-Disposition: attachment; filename=myfile.csv
This works fine in FF and IE7, downloading a CSV file as expected and opening a file picker to save the file, but Chrome does nothing. I confirmed that the server responds to the request, so it appears that Chrome will not process the response.
Curiously, all works as expected if I type the URL into Chromes address bar and hit <enter>.
FYI: Chrome 10.0.648.204 on Windows XP
In my case, I found that the "pending" status was caused by the AdBlock extension. The image that I couldn't get to load had the word "ad" in the URL, so AdBlock kept it from loading.
Disabling AdBlock fixes this issue.
Renaming the file so that it doesn't contain "ad" in the URL also fixes it, and is obviously a better solution. Unless it's an advertisement, in which case you should leave it like that.
I also get this when using the HTTPS everywhere plugin.
This plugin has a list of sites that also have https instead of http. So I assume before the actual request is made it is already being cancelled somehow.
So for example when I go to http://stackexchange.com, in Developer I first see a request with status (terminated). This request has some headers, but only the GET, User-Agent, and Accept. No response as well.
Then there is request to https://stackexchange.com with full headers etc.
So I assume it is used for requests that aren't sent.
I had some problems with pending request for mp3 files.
I had a list of mp3 files and one player to play them. If I picked a file that had already been downloaded, Chrome would block the request and show "pending request" in the network tab of the developer tools.
All versions of Chrome seem to be affected.
Here is a solution I found:
player[0].setAttribute('src','video.webm?dummy=' + Date.now());
You just add a dummy query string to the end of each url. This forces Chrome to download the file again.
Another example with popcorn player (using jquery) :
url = $(this).find('.url_song').attr('url');
pop = Popcorn.smart( "#player_", url + '?i=' + Date.now());
This works for me. In fact, the resource is not stored in the cache system. This should also work in the same way for .csv files.
I had the same issue on OSX Mavericks, it turned out that Sophos anti-virus was blocking certain requests, once I uninstalled it the issue went away.
If you think that it might be caused by an extension one easy way to try and test this is to open chrome with the '--disable-extensions flag to see if it fixes the problem. If that doesn't fix it consider looking beyond the browser to see if any other application might be causing the problem, specifically security apps which can affect requests.
I had a similar issue with application/json ajax calls. In ff/IE they were fine. In chrome in the Developer Network window Status was always (pending) because a different status code was being returned.
In my case I changed my Json response to send a HttpStatusCode of 200 then Chrome was fine and the Status Text changed to 200 OK.
For example using ASP.NET Web Api
return new HttpResponseMessage(HttpStatusCode.OK ) {
Content = request.Content
};
The Network pending state on time, means your request is in progressing state. As soon as it responds the time will be updated with total elapsed time.
This picture shows the network call is in processing state(Pending)
This picture shows the time taken in processing by network call.
The fix, for me, was to add the following to the top of the php file which was being requested.
header("Cache-Control: no-cache,no-store");
Same problem with Chrome : I had in my html page the following code :
<body>
...
<script src="http://myserver/lib/load.js"></script>
...
</body>
But the load.js was always in status pending when looking in the Network pannel.
I found a workaround using asynchronous load of load.js:
<body>
...
<script>
setTimeout(function(){
var head, script;
head = document.getElementsByTagName("head")[0];
script = document.createElement("script");
script.src = "http://myserver/lib/load.js";
head.appendChild(script);
}, 1);
</script>
...
</body>
Now its working fine.
Encountered a similar issue recently.
My App is in angular 11 and we have a form with some validators which have regex to validate the data. One of data element had a special character which the regex wasn't handling and it made the entire browser hung up. Infact, even though all network calls were successful with 200 Ok, chrome was not showing any response returned by the backend and was also showing the requests in Pending State when infact all network calls are successful, there was no console log errors or anything. Handling the regex fixed the issue.
After i found the issue, i googled more about it. Here is more explanation about it.
https://javascript.info/regexp-catastrophic-backtracking
I came across this issue when I was debugging a local web application. The issue turned out to be AVG Antivirus and Firewall restrictions. I had to allow an exception through the firewall to get rid of the "Pending" status.
In my case, a simple restart to my browser (chrome) and it worked straight away afterwards like magic!
Little bit of context, I happen to refresh my frontend web page and straight away went onto making a changes to my API which led it to restart. During that instance, the frontend was making calls to API which led into "pending" due to that API is reloading. Browser at this point cached that pending state. For me to get out of it is either I set no-cache (which I didn't want to) or simply restart the browser, I chose the restart.
A little background
I encountered such an issue when requesting an url in my Django project. The server is setup using Apache HTTP web server and basic auth for user authentication.
The url I was accessing required no authentication to access i.e. in my Apache config, I had set Require all granted on the url using the LocationMatch directive.
The issue
The url I was trying to access returned 200 status (in the Network tab in Chrome), but the static assets being used for styling of the requested webpage (css, javascript, font files etc.) associated with the request url were not loading and returned pending status.
In the meanwhile, the page loaded partially and still kept on loading. All this was happening in the presence of basic-auth dialog in browser, even though my url was granted all access.
What worked for me
Interestingly, as I entered my credentials and logged in, the requested page loaded all the static assets. This made it very clear to me that the static assets directory might NOT have the necessary access permissions.
Then, I granted the access to the static assets directory by updating my Apache config and then the requested url and the webpage loaded up fine (200 status) without any basic auth dialog OR pending status.
In my case, there's an update for Chrome that makes it won't load before you restart the browser. Cheers
I encountered the same problem when I request certain images from page. I use JavaScript to set the src attribute of an img object and if the network is poor pending will be displayed in the network panel of chrome developer window. I think it's due to the poor network.

Sharepoint - Multiple document upload - HTTP 'post' verb not allowed

When attempting to upload any number of documents, including very small files, seems to succeed- but subsequently redirects to an error page indicating the following:
/_layouts/error.aspx?ErrorText=The%20HTTP%20verb%20POST%20used%20to%20access%20path%20%27%2F%5Fvti%5Fbin%2Fshtml%2Edll%2FSiteCollectionDocuments%2FForms%2FUpload%2Easpx%27%20is%20not%20allowed%2E
The HTTP verb POST used to access path '/_vti_bin/shtml.dll/SiteCollectionDocuments/Forms/Upload.aspx' is not allowed.
Any ideas as to why HTTP POST would be denied for this operation?
Update:
Navigating directly to /_vti_bin/shtml.dll/SiteCollectionDocuments/Forms/Upload.aspx gives:
The XML page cannot be displayed
Cannot view XML input using style sheet. Please correct the error and then click the Refresh button, or try again later.

Error in event log looks like this:

PATH_TRANSLATED: C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\12\isapi\shtml.dll
The solution turned out to be removing the wildcard application mapping in IIS.
The url which receives the document upload via HTTP POST /_vti_bin/shtml.dll/SiteCollectionDocuments/Forms/Upload.aspx was being incorrectly mapped to C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\aspnet_isapi.dll and thus failing.
Update:
This solution tended to break other functionality, such as document deletion, and was scrapped during testing.
As it turns out, there was an HTTP module that was causing this url to be processed incorrectly. I added a bypass for /_vti_bin/shtml.dll/SiteCollectionDocuments/Forms/Upload.aspx and this solved the issue with no side effects.
The supported methods of uploading documents to SharePoint are:
Using web services (extensive example here)
Using RPC (example here)
Using the object model (example here)
Are you able to use one of these methods? If not can you please edit your question with more information about why and some sample code?
A guess at why the HTTP POST method isn't working is probably because it's for internal SharePoint use only.
