To optimize CPU, you may use switch with -regexp option.

If you want to use if, use elseif for each next conditions. If a condition matches, your code check next conditions.

 

Do not use multiple times [HTTP::uri], store it in a variable: [HTTP::uri] execute a command extracting uri from HTTP request.
