irule to strip the uri after apm completion it has to include the lengthy uri

Hi Sanjai,

to bypass the URI length limitations of APM, you have to use a Virtual-to-Virtual setup and then copy/restore the long URI into/from a custom HTTP header. Unfortunately this needs to be done on every single web request and not just during APM policy processing.

EXTERNAL_VIRTUAL

when HTTP_REQUEST {
    if { [string length [HTTP::uri]] >  4095 } then {
        HTTP::header insert "LONG_HTTP_URI" [HTTP::uri]
        HTTP::uri "/long_http_uri"
        virtual LONG_URI_VIRTUAL
    } else {
        pool site.domain.net
    }
}
when ACCESS_SESSION_STARTED {
    if { [HTTP::header value "LONG_HTTP_URI"] ne "" } then {
        ACCESS::session data set "session.server.landinguri" [HTTP::header value "LONG_HTTP_URI"]   
    }
}

Note: You can store long URI into the landinguri session variable. Its just the APM HUD filter that need to become tricked out...

LONG_URI_VIRTUAL

when HTTP_REQUEST {
    if { [HTTP::header value "LONG_HTTP_URI"] ne "" } then {
        HTTP::uri [HTTP::header value "HTTP_URI"]
        HTTP::header remove "HTTP_URI"
    }
    pool site.domain.net
}

Cheers, Kai
