Replace HTTP GET URL

try this (logging added so you can see what's going on in the /var/log/ltm file)

when HTTP_REQUEST {
    log local0. "HOST: [HTTP::host]"
     If you're only using IP, you don't need the 'string tolower' piece
    switch [HTTP::host] {
        "10.10.10.10" {
            log local0. "  URI: '[HTTP::uri]'"

             "HTTP::uri" doesn't include the "?" so we need to add it when doing URI query parsing
            set redir [URI::query "?[HTTP::uri]" yo] 
            log local0. "  YO: $redir"
            if { !($yo equals "") } {
                log local0. "  Redirecting to '$redir'"
                HTTP::redirect $redir
                return
            }
        }
    }
}
