Something like:

elseif {[LB::server pool] contains XXX_POOL"}{
HTTP::header replace Location [string map -nocase {"XXX" "uat_XXX"} [HTTP::header Location]]
HTTP::header replace Set-Cookie [string map -nocase {"/XXX" "/uat_XXX"} [HTTP::header Set-Cookie]]
             STREAM::expression {@XXXB@uat_XXX@}
                STREAM::enable }

Now throw another one into the mix coming from the same Pool. Like: uat_XXX1. So i guess the differences are the Location, but it doesnt appear to be working with that.
