how can I send a request to Google Server Side Tag Manager Instance?
With data-tag templates from Stape.io and other tools it worked.
But I want to send out a HTTP Request from Postman or something and see it on the Debug Mode on Server Side.
I always get an 400 and see nothing in debug mode.
Maybe you can help :) Thanks
I sent a get request through Postman to my Server Side instance and expect to see the request in the debug preview mode.
For a request to show up in the SGTM Preview Mode, it needs to have the X-Gtm-Server-Preview HTTP header.
To find yours, open the Preview Mode, click the three dots in the top right hand corner and click "Send requests manually".
I'm trying to fetch data from a website (https://gesetze.berlin.de/bsbe/search). Using Mozilla, I've taken a look at the network analysis. Usually, I'm just messing around with the parameters of the POST-Request to see how I might influence the response of the server. But when I simply re-send the request (making no changes at all), I'm getting HTTP-response 500. The server answer states as message: security_notAuthenticated.
Can anyone explain that behaviour? The request is done by the same PC, the same browser in the same session, and there is no login function on that website. Pictures shown below.
Picture 1 - Code 200
Picture 2 - Code 500
The response security_notAuthenticated indicates, that your way of repeating the request omits some authentication-related information.
When I repeat the request, using Mozilla Firefox's "Resend" or "Edit and resend" function, the Cookie header is not sent with the request. Although it occurs in the editable header list when using "Edit and resend" it's missing when watching the actual sent request. I'm not sure whether this is a feature or a bug.
When using Firefox's "Use as Fetch in Console" function, the header will automatically be included and you still have the ability to change the headers and the body. The fetch API is a web standard and some introductory material about fetch can be found on MDN.
If you want to do custom requests, in the browser, fetch is a good option.
In other environments and languages you usually use some HTTP client (just search the web for "...your language... http request" or similar, you will find something).
I am trying to login to a website and I need to see the HTTP transactions when I log in by browser then simulate procedure by my application in java using Apache Httpclient.
Are there any tools or software for this? If there are any, where can I download them?
If you're using Google Chrome as your browser, this is a feature in Chrome Developer Tools
Simple press F12 and switch to the Network tab. Here you can get headers and content of HTTP requests. You can also right click the HTTP request and get it as cURL (cmd or bash)
You can combine this with the Chrome extension Postman which can help you generate the code for a number of programming languages (including Java OK HTTP and Java Unirest).
I don't know exactly when this changed but probably around version 18...
In the past when a flash app (SWF) would make an AJAX call i can see the call logged and the response (which would be JSON) would be available in both the preview and response sub-tabs of the Network tab - mind you the response would not be pretty-printed tree in the preview tab.
Now, I see the AJAX calls and all the header info, but the Preview and Response sub-tabs are empty!
Is there a flag/setting that would log these? (I'm on Chrome 20)
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.
