Hi,

thanks for this irule. A few notes:

  • If other irules are attached to the same virtual server I suggest to attach a priority to the HTTP_REQUEST event to ensure it runs before any irule changes headers.

    priority 100
when HTTP_REQUEST{

  • If you would like to add TCP ports of the client side connection to the header change the following:

    • line 33:

      lappend FFOR_HEADER_LIST "for=$CLIENT_ADDR:[TCP::remote_port]"

    • line 78:

      set FBY_HEADER "by=$BY_ADDR:[TCP::local_port]"

Regards, René
