Hi,

A space can be encoded as + or %2b in some URL encoders or more typically as %20. Do you want check the full URI or just the path for these characters? Here's an example for checking the path:

 
 when HTTP_REQUEST { 
     Check if path contains +, %2b or %20 
    switch [string tolower [HTTP::path]] { 
       "*+*" - 
       "*%2b*" - 
       "*%20*" { 
           Path contained a "space" character. Do something? 
          log local0. "Found space character in path: [HTTP::path]" 
       } 
    } 
 }
