iRule to modify http response

Hello all,

Seeking some assistance with modifying a http response from a server back to a client.

Senario is as follows (All web traffic)

• VS_A answers on 443 and sends to pool members on 9999
• VS_B answers on 888 and sends to same pool members on 7777
• When browsing to VS_B, there is a function that is on the site that responds with the public url of VS_A (ex https://www.acme.com:9999) instead of https://www.acme.com and hence causes a timeout because the clients are not able to access that port directly.

I am seeking to remove the port but keep all uri information.

Additionaly

Do I need any specific settings for the VS in order for this to work?

I have http-wxff profile I have sslclient profile I have sslserver profile

am I missing anything obvious?

Update....... I am trying below

I am attempting to modify a server response back to the client. I am attempting to remove the port from the url the client receives while still perserving the case and uri information.

When attempting this I notice no 302 response (Using firefox) and no location information. Seeking help to get this sorted.

when HTTP_REQUEST { Disable the stream filter for requests STREAM::disable

 Remove this header to prevent server from compression response
HTTP::header remove Accept-Encoding

} when HTTP_RESPONSE { set internal_host "xxx.yyy.com" set external_host "boy.girl.com" Rewrite the Location header for redirects if { [HTTP::header exists Location] }{ HTTP::header replace Location [string map "$internal_host $external_host" [HTTP::header Location]] }

 Rewrite the response content using a stream profile if it is text 
if { [HTTP::header Content-Type] contains "text" } { 

     Set the stream expression with the find/replace strings 
    STREAM::expression "@$internal_host@$external_host@" 

     Enable the stream filter 
    STREAM::enable 
} 

}
