Developer’s Description

By Gareth Hunt
Add, edit, and filter HTTP request headers.

Modify Headers can modify the user agent string and add headers to spoof a mobile request (e.g. x-up-calling-line-id). Take a look at the help tab of the Modify Headers window. Some people think that 'user-agent' is a custom way of specifying the user agent string.
