Multi-part Irule

Here's some slightly updated code:

 

 

 

 
 when HTTP_REQUEST {  
   log local0. "[IP::client_addr]:[TCP::client_port]: New request to [HTTP::uri]"  
    Check if URI contains /forms  
   if {[HTTP::uri] starts_with "/forms"} {  
     if { [HTTP::host ne "site2.com" } { 
       HTTP::redirect "http://site2.com[HTTP::uri]" 
     } else { 
       log local0. "[IP::client_addr]:[TCP::client_port]: active members: [active_members SECOND_POOL]"  
        Use the second pool if it has available members  
       if {[active_members SECOND_POOL] > 0}{  
         pool SECOND_POOL  
       } else {  
         Second pool was down, so use the third pool  
        pool THIRD_POOL  
       }  
     }  
   } 
 } 
 

 

 

Basically this is the same iRule, except that it performs a host check, too. Basically, you set both domains to point to the VIP address. Then, when traffic comes in from site1.org with /forms at the start of the URI, it will do an HTTP redirect to site2.com while maintaining the exact same URI (we already know it contains forms, so we don't need to rebuild it or strip forms out or anything, we just keep the whole thing intact as is). It will then hit the same VIP, again, and process through the second half of the iRule, as it won't get caught by the Host check this time. Now it'll hit the pool logic portion that elah built for you, and everyone should be happy.

 

 

Make sense?
