See Question&Answers more detail:osTo modify the header with Fiddler:
1- Open Fiddler Web Debugger and in the menu toolbar go to Rules
->Customize Rules...
(shortcut is Ctrl + R). It opens the CustomRules.js
file. Fiddler may suggest you to download Fiddler ScriptEditor but you can edit it with any text editor (I use notepad++)
2- Find OnBeforeRequest(oSession: Session)
in the script file.
3- You can add a new header by adding oSession.oRequest["NewHeaderName"] = "New header value";
to OnBeforeRequest
function. Also, to remove a header, use oSession.oResponse.headers.Remove("HeaderName");
function.
