Hi Vova V,

I'm using [URI::basename] command to parse the last element of a given HTTP path. But keep in mind that some WebServices (e.g. ".asmx/method" ".json/method) don't like trailing slashes. So you may want to setup some exclusions...

This is the code I'm using for some SharePoint Sites...

 

when HTTP_REQUEST {
    if { [set uri_base [URI::basename [HTTP::path]]] eq "" } then {
         if { $debug } { log -noname local0. "The URI::basename is a /Folder/." }
    } elseif { $uri_base contains "." } then {
         if { $debug } { log -noname local0. "The URI::basename is a *.* File." }
    } else {
         if { $debug } { log -noname local0. "The URI::basename is a /Folder (without trailing slash)." }
        switch -glob -- [string tolower [HTTP::path]] "*.asmx*" - "*.json*" - "/_*" - "*/_layout*" - "*/_vti_bin*" {
             if { $debug } { log -noname local0. "The HTTP::path is exempted..." } 
        } default {
             if { $debug } { log -noname local0. "Adding a trailing slash to the URI::basename." }
            HTTP::path "[HTTP::path]/"
        }
    }
}

 

Cheers, Kai
