Add HTTP headers to requests for backend servers
The simplest and most light-weight way to test backends with multiple virtual servers.
The common case is a webserver that can serve multiple websites. If you don't have DNS setup, or DNS refers to a reverse proxy, this extension will allow you to talk directly to the backend server, overwriting the http host header.
Servers: proxy.example.com web01.example.com
websites: foo.com, bar.com
Objective: you want to test how web01.example.com responds to requests to foo.com, but foo.com is already set up in DNS to go to proxy.example.com
Solution: Set the host value to web01.example.com, set the host header to foo.com and browse to http://web01.example.com
This extension will set the host header as though you were accessing http://foo.com
