AN IRULE THAT INCLUDES ANOTHER PORT AS PART OF CONNECT METHOD PLUS 443

I'm using my LTM as transparent proxy for my users to get to the internet. How do i include a non-standard port in the CONNECT method list,apart from 443.

This is the current irule, i want to include another port, say 5057 to the list.

 First check to see what method we're handling through the proxy.
 We need to process CONNECT a little differently than other HTTP proxy
 methods, and we need to discard requests that come through with
 unsupported methods.
 Coming out of this section will be:
  - $host : hostname or bare IP address requested
  - $port : port of the connection requested
  - $new_path : normalized URI with the proxy format stripped
switch -- [HTTP::method] {
    "CONNECT" {
        set is_http 0
        set is_https 0
        set request_log_line ""
        set original_request [HTTP::uri]
        set host [string tolower [getfield [HTTP::uri] ":" 1]]
        set port [getfield [HTTP::uri] ":" 2]
        if {$port eq ""}{
            set port 443
        }
        set new_path [HTTP::uri]
        HTTP::header remove "Proxy-Connection"
        HTTP::cookie remove "MRHSession"
        if { $static::proxy_debug_L4_VIP_GPRS_TRANSPARENT } { log local0. "Connect request from $host to $port." }
        set http_version [HTTP::version]
        set is_connect 1
        set is_https 1
    }
