x-Forward-For HTTP client IP

Hello, I'm not sure how to configure my VIP to forward the client IP to the hosting servers given our VIP doesn't actually have a pool assigned, but uses an iRule instead.

We have a two VIP objects (HTTP/S) with no pool assigned to either. The HTTP VIP we're using to intercept and redirect traffic to HTTPS (via an iRule). On the HTTPS object we are using an iRule to route client traffic to 7 different pools. I tried enabling the x-forward-for option on the HTTP profile on the HTTPS VIP, but that didn't work. I added an iRule to the HTTPS VIP to handle the x-forward, that didn't do it either. The iRule is included below. Oh, the HTTPS object has both client and server side SSL configured.

Any suggestions? Note: I'm an F5 scripting novice.

Thanks in advance!

iRule on VIP to direct traffic to pools:

when HTTP_REQUEST {


 if { [string tolower [HTTP::host]] contains "cpacd." } { 
   if {[active_members ACD_CPACD_Pool] > 0} { 
      pool ACD_CPACD_Pool
   } else { 
      HTTP::redirect "http://maintenance.acc.org" 
      event disable all 
   } 
 }
 elseif { [string tolower [HTTP::host]] contains "hfacd" } { 
   if {[active_members ACD_HFACD_Pool] > 0} { 
      pool ACD_HFACD_Pool
   } else { 
      HTTP::redirect "http://maintenance.acc.org" 
      event disable all 
   } 
 }
 elseif { [string tolower [HTTP::host]] contains "afacd" } { 
   if {[active_members ACD_AFACD_Pool] > 0} { 
      pool ACD_AFACD_Pool
   } else { 
      HTTP::redirect "http://maintenance.acc.org" 
      event disable all 
   } 
 }
 elseif { [string tolower [HTTP::host]] contains "fsedacd" } { 
   if {[active_members ACD_FSEDACD_Pool] > 0} { 
      pool ACD_FSEDACD_Pool
   } else { 
      HTTP::redirect "http://maintenance.acc.org" 
      event disable all 
   } 
 }
 elseif { [string tolower [HTTP::host]] contains "acdanalytics" } { 
   if {[active_members ACD_ACDANALYTICS_Pool] > 0} { 
      pool ACD_ACDANALYTICS_Pool
   } else { 
      HTTP::redirect "http://maintenance.acc.org" 
      event disable all 
   } 
 }
 elseif { [string tolower [HTTP::host]] contains "cpdmt" } { 
   if {[active_members ACD_CPDMT_Pool] > 0} { 
      pool ACD_CPDMT_Pool
   } else { 
      HTTP::redirect "http://maintenance.acc.org" 
      event disable all 
   } 
 }
 elseif { [string tolower [HTTP::host]] contains "hfdmt" } { 
   if {[active_members ACD_HFDMT_Pool] > 0} { 
      pool ACD_HFDMT_Pool
   } else { 
      HTTP::redirect "http://maintenance.acc.org" 
      event disable all 
   } 
 }
else {
      HTTP::respond 404 content "Unrecognized request to [HTTP::uri]" "Content-Type" "text/html" 
    }
}

iRule configured on VIP to run after the above iRule to forward client IP (didn't work).

when HTTP_REQUEST {
HTTP::header insert X-Forwarded-For [IP::remote_addr]
}
