Unique HTTP Proxy Situation - suggestions?

Operating System: LTM 9.3.1 (ugh)

 

 

Situation: We have a single externally available virtual server that handles all of the traffic to our main web presence (www.company.com) and an iRule that directs requests to the appropriate pool based off of URI. This rule uses when HTTP_REQUEST and captures host and uri to variables, using a switch statement against them -- pretty straightforward.

 

 

 

A need has arisen to continue to use the www.company.com external name, but direct certain URIs to a third-party without re-directing to a different domain name. Meaning, the client browser always appears to be accessing www.company.com/thirdparty, but the actual flow of traffic would be user -> our external F5 Virtual Server -> third party.

 

 

 

My initial suggestion was to grab the www.company.com/thirdparty request, rewrite it as thirdparty.company.com/thirdparty and handle it that way, but it appears the business would prefer we proxy this traffic. And hence, this forum post!

 

 

 

Is this possible? Any starting points if so?

    is it something like this? 

    [root@ve1023:Active] config  b virtual bar list
virtual bar {
   snat automap
   pool foo
   destination 172.28.19.79:80
   ip protocol 6
   rules myrule
   profiles {
      http {}
      tcp {}
   }
}
[root@ve1023:Active] config  b pool foo list
pool foo {
   members 200.200.200.101:80 {}
}
[root@ve1023:Active] config  b rule myrule list
rule myrule {
   when HTTP_REQUEST {
        if {[string tolower [HTTP::host]] equals "www.company.com"} {
                if {[string tolower [HTTP::uri]] starts_with "/thirdparty"} {
                        HTTP::header replace Host "thirdparty.company.com"
                }
        }
}
}
