How does the extension work?

If you add your own host config, the extension will add your configured payload data to the requests for this specific host only.

The extension only adds your user-defined header data, if the host of a browser tab matches the one from your host config.

All data of this tool is stored in the internal storage of the browser extension itself. Nothing is stored external.

Where to use the extension?

The best place to use custom HTTP headers is on the web server level. You can set coditions in the server config files of your favorite server like Apache, Nginx, or Litespeed. We added some implementation examples below.

Additionally you can add conditions programatically in your scripts in PHP, Python, Perl, aso. You find examples for this also on this page.
