Problem with bots redirect

i think the irule could be okay.

anyway, according to sol9800, the irule should select a pool under every possible condition.

sol9800: Using an iRule to load balance HTTP requests to multiple pools

http://support.f5.com/kb/en-us/solutions/public/9000/800/sol9800.html

e.g.

when HTTP_REQUEST { 
   if { ([matchclass [string tolower [HTTP::header User-Agent]] contains googlebot]) and ([HTTP::uri] contains "/blog")} { 
      pool xyz 
   } elseif { [matchclass [string tolower [HTTP::header User-Agent]] contains robots] } { 
      pool NeimansBOT 
   } else {
      pool default_pool
   }
}
