ASM Referrer Support - iRule

Hi Blaisure,

you can try the iRules below...

when HTTP_REQUEST { 
    set referer [HTTP::header "Referer"]
}

when HTTP_REQUEST_SEND { 
    if { $referer starts_with "http" } then { 
        clientside{ 
            HTTP::header replace "Referer" $referer 
        } 
    } 
}

There is no need to test the existence of the

[HTTP::header]

during

HTTP_REQUEST

before accessing it. You will either get a "" (nothing) or a certain "referer_value" back. In

HTTP_REQUEST_SEND

you would then still check for valid referer information before writing it back to the request.

Good luck with your iRules solution!

BTW: Didn't test the functionality. But at least the formating should be now correct.

Cheers, Kai
