Manipulating the X-Forwarded-For header

You can control what happens to the X-Forwarded-For HTTP header via the Create a new request setting page on the Requests settings area of the Settings page. From the X-Forwarded-For menu, select one of the following behaviors:

  • Append - Appends the client IP to the X-Forwarded-For header.
  • Append All - Appends the client IP (and edge-cache IP, in case of shielding) to the X-Forwarded-For header. Creates the header if it does not exist yet.
  • Clear - Clears the X-Forwarded-For header.
  • Leave - Leaves the X-Forwarded-For header as is, if it is present.
  • Overwrite - Overwrites the X-Forwarded-For header with just the client IP.
