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.

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.

I have a legacy web application. The app needs to be opened in IE while the user opens it from Edge Chromium. I've added the URL to the EM site list XML on a NAS share. This works great for other legacy applications we have.
However, this application uses a HTTP POST request.
When a user navigates in Edge to the web application, it loads fine in a new IE11 screen.
But when you use the search, it opens in a new Window and it seems the parameters from the HTTP POST request are not included. This results in a null request.
Is there any setup needed to include the HTTP post request in IE mode? I can't find this anywhere in the MS documentation.
We've replaced the post request with a get request and solved the issue this way
We had the same symptoms. I did not verify that the http method was changed from POST to GET, but the form variables from a POST operation were not being transmitted to the next page.
We were able to get this working by adding the source page (the one with the form variables in it) to the Enterprise Mode Site List in Edge.
In Edge, paste the following into the address bar (without the quotes): "edge://compat/SiteListManager"
I checked the box to Allow Redirects and also used IE5 Document mode as the Compat Mode because that is what was indicated by f12 tools when running the same page in real IE 11.

I am using HttpClient in client side blazor app, but when i am doing a call to an API that some times isnt there (because its an image search to an azure blob storage) it returns a 404 error which is fine. My issue is, is that the 404 error is then being displayed in the browser console (google chrome for me), is there a way of preventing this as i dont want the user to know it is a 404 instead i want to act upon that 404 my self by displaying a default image.
Here is my offending but simple code that then logs to the browser console.
await client.GetAsync("URL of Image");
Can you give a bit more context and code examples? Are you handling the HttpClient errors in a try/catch block?
As far as I know, the browser will always log any 400-500 errors in the console, and you cannot disable this output. It's called the developer tools for a reason. Also, what is keeping users from viewing the network tab in those same tools?
I honestly think this is a non-issue unless you are naming files something suspicious..
When typing a web link into the safari URL field, the browser attempts to prefetch all links it has previously seen before, both GET and POST.
This causes each and every web link a server supports that is listed in the dropdown as a possible completion to be activated. This is problematic. For example, if a web site has authentication with an /auth/logout link for logging out, then this can cause the link to be activated if it appears in the dropdown, logging the user out unintentionally.
Many browsers send a specific header (eg. 'Purpose: Prefetch' in chrome) that allows the server side to filter prefetch/preload requests (eg. return a 503) but Safari doesn't seem to send any distinguishing header field. It also seems to try to prefetch POST requests, which seems very broken to me. Get requests are notionally at least idempotent, but POST requests are supposed to be understood to be data changing.
Has anyone got a solution to this? Please don't suggest that the browser preload feature can be turned off by the end user - that ISN'T a solution from a service delivery perspective.
Has anyone got an explanation as to why browsers would do this and NOT signal the purpose in a header field? (I get why prefetching is a useful Ux capacity, but not why its useful while typing URLs, especially for URLs already previously downloaded and thus capable of returning prefetching metadata that would allow a server to selectively disable the capability where appropriate) From what I can tell, this kind of functionality started to appear with header fields included, but some browsers have removed this signature. why? It seems to be dreadfully broken to me.
thanks.
I've got a weird bug and wondered if anyone else can think of a cause.
Scenario: -
User tries to access restricted content, gets a turn away page with 403 status code
User logs in
User tries to access content again but should be allowed, browser returns cached turn away page and 403 response (no hit registered on server).
CTRL+F5 or wait a while, browser returns correct content.
This is happening in Firefox and Chrome, I haven't tried Internet Exploder.
I have only reproduced the issue once on my machine whilst on a Skype call with the testers, they can reproduce it every time. They are based over in India though and have a much slower connection to our test site. Could that be a cause?
I saw a related question but that was caused by Squid proxy, i'm not behind a proxy (although testers might be).
I'm loathe to add cache control headers as browsers shouldn't cache a 403 according to the HTTP spec but I need to guarantee with that when a user logs in they get the correct content.
Any thoughts on what might be the cause would be greatly appreciated. In the meantime I'll add some cache control headers to the turn away page just to see if that helps.
I am experiencing a strange situation where Firefox is loading a page 2 or 3 times just to show it once. I have looked into obvious things like empty image tags and such, but can't figure it out.
Using firebug, I can see in quick succession, the browser is getting a 200 Aborted and then the 200 OK, before loading the other elements of the page. Looking at my server logs, I only see the 200 OKs, nothing that is like an abort. Does anyone know why this happens? It happens with simple link clicks, no ajax in play when this occurs. This is causing extra server load, and also double activity for operations that are not idempotent.
Firebug causes a second HTTP GET request of #fontface font-files
http://code.google.com/p/fbug/issues/detail?id=4649
I had the same issue but that whose Firebuq buq :)
The only thing I have seen close to this is bad .htaccess redirects. If you are using a linux server, check all of the .htaccess files in the folder that the file is in, the folders that you are linking to and also all the parent folders.
200 Abort is sent when you call the abort() method on XMLHTTPRequest objects. Maybe you should post some related JS code or look for cases where abort() is being called.
The issue is completely related to firebug. Try using Firefox's in-built Web Console with "Net" option enabled.
In my case there was a network issue blocking the https: transfers (SSL session not trusted). Once the credentials were accepted, the transfers changed from ABORTED to Success.
Check that there arent empty src properties in img tags.
