Hi Mohamed,

Thanks for your reply.

Basically, we want to load balance (round robin for e.g) to 2 servers in the member pool - but before passing it on to the servers, we need the Virtual Server to re-write the URL path to a different specific folder on each server:

The reading I've done so far suggests when we use the HTTP::redirect iRule, the F5 replies directly to the client and doesn't load balance (even then sending to 2 different locations is a big ask). 

In the mean time, we are looking into completing this task using re-directs on the individual servers, as I think that makes more sense.

Might be as easy as this:
Not sure if LB::server name returns the correct information 

when LB_SELECTED {
#  log local0. "server [LB::server name]"
  set path "/folder/folder/[LB::server name]"
  HTTP::host "[LB::server name].local.domain"
  HTTP::path $path
}
