Updated and tested in my lab, this could work for you.

when HTTP_REQUEST {
    set uri "/[getfield [HTTP::uri] "/" 2]/"
    HTTP::uri [string map " $uri / " [HTTP::uri]]
}

It will remove the first folder in the URI path.

Pool selection can be done either with a switch or a datagroup. A datagroup will scale easier as you will just have to add all your root apps like css to the data group to have pool selection based on it. Switch: when HTTP_REQUEST { set uri "/[getfield [HTTP::uri] "/" 2]/" HTTP::uri [string map " $uri / " [HTTP::uri]] switch [getfield [HTTP::uri] "/" 2] { "css" - "apps" - "containers" { pool [getfield [HTTP::uri] "/" 2] } default { pool *default_pool* } } } Datagroup: when HTTP_REQUEST { set uri "/[getfield [HTTP::uri] "/" 2]/" HTTP::uri [string map " $uri / " [HTTP::uri]] if { [class match [getfield [HTTP::uri] "/" 2] equals *datagroupname*] }{ pool [getfield [HTTP::uri] "/" 2] } }
