ModHeader tutorial

Here is a short tutorial to help you get started with ModHeader. This tutorial should take 1-2 minutes to complete.

In this tutorial, we will try to add the X-Forwarded-For request header. X-Forwarded-For is a request header that tells the server which IP originally made the request. By changing the X-Forwarded-For header, you can tell the server to treat the request as if it is coming from a different IP. Not all servers will trust X-Forwarded-For blindly, but it can be useful for testing and development.

How to add X-Forwarded-For request header

  1. To get started with ModHeader, click on the ModHeader icon in the browser extension area. If you have not installed ModHeader yet, you can install ModHeader here.
  2. If this is your first time using ModHeader, you should already see an empty row under Request headers. If not, click on , and select Request header to add an empty row.
  3. Enter X-Forwarded-For as request header name.
  4. Enter as request header value.
  5. This is how ModHeader should look like at this point:
  6. It appears that the X-Forwarded-For request header value is not added. Try changing the value in ModHeader and try again. Review this step again if needed.

Additional tips

  • The request header we added is being sent to all HTTP requests. This may not be desirable as we may leak sensitive data to third party websites.
  • To reduce the risk, you can add URL filters or tab filters by clicking on the button, then select the desired filter to add.
  • ModHeader can change X-Forwarded-For header, but it will not hide your IP, and may not work on all servers. To completely change your IP, try using NordVPN .
