Alter your HTTP request headers on the fly

Header-Editor is an extension that will allow you to create and use arbitrary HTTP headers in Chrome. The following permissions are needed for Header-Editor to run: - webRequest - Used to access the requests being sent out. - webRequestBlocking - So that headers are modified before being sent. - <all_urls> - All URLs are asked for since the extension cannot know ahead of time where it will be needed. Note: Response headers do not appear in the Network Inspector, however they are supplied to your code. For more details, see: - http://hexcoder.us/2013/08/08/response-headers-and-chrome-extensions/ - https://code.google.com/p/chromium/issues/detail?id=258064

Unable to remove the original header value from the original request / response, and the popup design is not very ergonomic.

This how to view response headers: var req = new XMLHttpRequest(); req.open('GET', document.location, false); req.send(null); var headers = req.getAllResponseHeaders().toLowerCase(); alert(headers);

If you set a header it works the first time (on the server, you can see the header arriving). But then, if you alter the header value, it still sends the original value. It kept sending a particular value even after I deleted that header. Maybe you are supposed to restart the browser after changes but I'm not going to do that.
