No, there is no way to disable or close a connection from the Network panel. Source: DevTools Engineer.

If you have a reference to the WS connection, though, you can close it via the Console using its JS API.

You can close idle and flush your inactive socket pools in the Net Internals page in Chrome. However, this unfortunately only closes your active sockets by the looks of it.

You would have to use the [WebSockets API][2] and call [`close()`](https://developer.mozilla.org/en-US/docs/Web/API/WebSocket#close()) on a reference to an existing socket to close it explicitly. Otherwise, killing the process with the active socket is all I can think of.

I have a repository that uses `Travis CI`, and in the `.travis.yml` there I have this line:

    script:
    - vim -Nu &lt;(cat &lt;&lt;-EOF
      set nocompatible |
      filetype off
      EOF
      ) -c &#39;Script&#39; &gt; /dev/null

Sadly this doesn&#39;t work, as this is transformed into a single line and is executed like this:

    vim -Nu &lt;(cat &lt;&lt;-EOF set no compatible | filetype off | EOF ) -c &#39;Script&#39; &gt; /dev/null

This makes the `EOF` tag not working, as `EOF` needs to be in a single line.
An alternative would be to just use normal quotes like this:

    script:
    - vim -Nu &lt;(cat &#39;set nocompatible |
      filetype off
      ) -c &#39;Script&#39; &gt; /dev/null

Which works, and is fine, but I feel there must be a way to insert newlines into a `.travis.yml`. I have an alternative now, but I may not in the future. So how do you do it?

I&#39;m having this problem: **No service for type &#39;Microsoft.AspNetCore.Mvc.ViewFeatures.ITempDataDictionaryFactory&#39; has been registered.** In asp.net core 1.0, it seems that when the action try to render the view i have that exception.

Is there any way to disable web socket connections or end a web socket connection through Chrome&#39;s developer tools network tab?

I&#39;ve noticed that turning throttling under the network tab to *Offline* doesn&#39;t affect web socket connections that have already been established.  It only prevents traditional HTTP requests from going out.

There&#39;s a question [here][1] related to this, but it&#39;s woefully outdated.

I&#39;ve created a new Foundation 5 project through bash, with `foundation new my-project`. When I open the index.html file in Chrome an `Uncaught TypeError: a.indexOf is not a function` error is shown in the console, originating in `jquery.min.js:4`.

I created the project following the steps on the foundation site, but I can&#39;t seem to get rid of this error. Foundation and jQuery look like they are included and linked up correctly in the index.html file, and the linked app.js file is including `$(document).foundation();`

Does anyone know what is causing this error? and what a solution might be?

When using `window.onbeforeunload` (or `$(window).on(&quot;beforeonload&quot;)`), is it possible to display a custom message in that popup?

Maybe a small trick that works on major browsers?

By looking at existing answers I have the feeling this was possible in the past using things like `confirm` or `alert` or `event.returnValue`, but now it seems they are not working anymore.

So, how to display a custom message in the beforeunload popup? Is that even/still possible?

Why does my chrome developer tools show &quot;Failed to show response data&quot; in response when the content returned is of type text/html?

What is the alternative to see the returned response in developer tools?

Chrome dev tools fails to show response even the content returned has header Content-Type:text/html; charset=UTF-8

Test browser: 
Version of Chrome: 52.0.2743.116

It is a simple javascript that is to open an image file from local like &#39;C:\002.jpg&#39;
   
    function run(){

       var URL = &quot;file:///C:\002.jpg&quot;;

       window.open(URL, null);

    }
    run();

Here is my sample code.

Please give me any suitable suggestions.

Cannot open local file - Chrome: Not allowed to load local resource

I&#39;m trying to do a `hard reload and empty cache` in Chrome because a previously loaded site keeps coming up on the `localhost` port I&#39;m using. Problem is the the right-click options seems to have stopped working, ie. nothing happens when I right-click on the refresh button and I can only left-click and reload the page normally. I had the option before so I know it&#39;s not the Chrome version I am using. It&#39;s pretty annoying. Anyone know what&#39;s happening here? Thanks in advance!

Chrome refresh right-click reload options not available

I&#39;m building a web application which uses CORS to communicate with it&#39;s server.

This means that every request is preceded by one with OPTIONS method.

Is it possible to filter those out in inspector? It makes a lot of unnecessary clutter on network tab.

Is it possible to filter options requests in chrome inspector?

When using the option &quot;toggle device scrollbar&quot; in the Chrome inspector, whenever you type a new width/height, the window zoom adjusts for that width/height automatically. This is an incredibly frustrating UI, as I don&#39;t want the zoom to adjust... ever. The only way to avoid this is by resizing the responsive window by dragging the side borders.

Is there a way to turn the auto zoom off?

My current version of chrome: Version 54.0.2840.98 (64-bit)



How to stop chrome responsive inspector from changing the zoom?

I am working on a project using Typescript and some of the ES6 features exposed by Typescript like ES6 String Literals e.g. `` `Something ${variable} Something else` ``.

Whilst debugging a problem I dropped a breakpoint into my typescript file to step through it in the source panel, which usually works fine.

But Chrome Dev Tools has an issue with ES6 String literals and doesn&#39;t seem to recognise the end of an ES6 String literal.

Instead all code following the string literal is marked red (string highlighting in debugger) and blocked from variable inspection as chrome debugger seems to think it is all one massive string.

Has someone encountered this issue, found a fix or knows whether this is on Google&#39;s roadmap for Chrome Dev Tools?

**EDIT 1:**  
Looks like this issue is currently being worked on by the Chromium team. See issue report for updates:  
[bugs.chromium.org/p/chromium/issues/detail?id=659515][1]

**EDIT 2:**
Bug has been open for quite some time, but doesn&#39;t seem to have been prioritised. If you experience the issue go to the chromium link above and star/comment on it with helpful info to move it into focus of the Dev Tools team.

Chrome Dev Tools Issue With ES6 String Literals/Typescript

Is there any way using chrome dev tools to find where an http request (ajax) was made?
I have a large project with many requests happening in different files. There&#39;s a particular request that I want to be able to inspect, I&#39;ve found it on the Network tab, but there doesn&#39;t seem to be any way to find where in the code was this request started.
