Irule to rewrite URL

Sorry I just noticed that you do not want a redirect but a pool assignment The key is you want to remove /sav/dtl/ and /sav/jog to remove these characters use the string range command. pool1 is the first server and pool 2 is the second server. Make sure the pool are using the 8081 port

when HTTP_REQUEST {

set Vuri [ string tolower [HTTP::uri]]

if { $Vuri starts_with "/sav/dtl/"} then {
    set HTTP::uri to start 8 Characters from the start og it self
    HTTP::uri [string range [HTTP::uri] 8 end]
    pool pool1
}
elseif {$Vuri starts_with "/sav/jog/" } then { 
    HTTP::uri [string range [HTTP::uri] 8 end]
    pool srvpool2
}

}
