Hi Steve,

the 
findstr
function will help: 
when HTTP_REQUEST { 
    if { [string tolower [HTTP::host]] equals "this.example.com" } {
        if { [string tolower [HTTP::path]] starts_with "/documents/" } {
            HTTP::redirect "http://serverA:8080[findstr [string tolower [HTTP::uri]] "/documents" [string length "/documents"]]"
        } elseif { [string tolower [HTTP::path]] starts_with "/logs/" } {
            HTTP::redirect "http://serverB[findstr [string tolower [HTTP::uri]] "/logs" [string length "/logs"]]"
        } elseif { [string tolower [HTTP::uri]] starts_with "/reports/" } {
            HTTP::redirect "http://serverB[findstr [string tolower [HTTP::uri]] "/reports" [string length "/reports"]]"
        } else {
            HTTP::redirect "http://this.example.com[HTTP::uri]"
        }
    }
}

There are smarter solutions based on the 

switch
command (jump table).

Please note, that there is no action defined, if the initial condition (host name) does not match. Thanks, Stephan
