ProxyPass - Reverse Proxy / Backend URL rewrite.

Hi Steve,

 

What are you asking won't be accomplished without the iRules so I want to apologize upfront but I am going to start throwing you up some iRule code. It sounds like you don't want re-write but you basically want a webproxy

 

 

Here is a piece of untested code

 

 

However, there are some items you will need to address before hand.

 

- The ADC must have access to internet

 

- You must make sure that you have configured the ADC for DNS local lookup as described in SOL5299 located in ask.f5.com (Don't ask me how I remember this stuff 🙂 )

 

 

Obviously this is a simple example but my hope at the very least is that it generates ideas in this discussion.

 

 

 

when HTTP_REQUESTED {

    if { [HTTP::host] eq "www.yahoo" } {
          NAME::lookup www.google.com
         Wait until name resolution is completed before sending you to the new page  
        HTTP::collect
        }
}

when NAME_RESOLVED {
   set response [NAME::response]
   resolved www.google.com to an ip address via load balancer and now use that in the node command.
 
  switch [llength $response] {
      0 {
          HTTP::respond 500 content "Couldn't Process Request}
      default {
             HTTP::uri "[HTTP::uri]"
              HTTP::header replace "Host" "www.google.com"
             node [llindex $response 0] 80
          }
   }
HTTP::release
}

 

 

 

I hope this helps
