I am trying to use Charles (http://www.charlesproxy.com) to add a header to every HTTP request I execute in a browser. The web app I am using is relying on a header to work correctly. I have setup a rewrite rule to add a header like this:
Charles error log shows that the request is matched and it says it added the header:
2017/05/24 16:34:04 INFO com.xk72.charles.tools.rewrite.RewriteFilter CONNECT https://www.googleapis.com Testing: Add Header: MY_HEADER:MY_HEADER_VALUE
2017/05/24 16:34:04 INFO com.xk72.charles.tools.rewrite.RewriteFilter CONNECT https://www.googleapis.com Matched: Add Header: MY_HEADER:MY_HEADER_VALUE Rewrite: MY_HEADER_VALUE
But when I try to open the web app in question in Chrome by typing in a url and when I inspect the traffic in Chrome Dev Tools, I don't see the header and my app doesn't work.
