XFF Alternative Names

Hi!

You could use an irule:

when HTTP_REQUEST {
    if { [HTTP::header exists "X-Forwarded-Alternate"] } {
        If the user already has specified this header then
        we want to overwrite it 
        HTTP::header remove "X-Forwarded-Alternate"
        HTTP::header insert "X-Forwarded-Alternate" [IP::client_addr]
    }
}

Hope that helped.
