Yet another URI rewrite

With our company divesting, I've been tasked with identifying incoming remote_addr, then intercepting certain URI content and modifying that URI on the fly.

 

 

Example: http://www.abc.com/com/usa/wheretogo

 

 

identify the com/usa and change it to com/usanew with any prepended or appended URI content remaining the same.

 

 

Result: http://www.abc.com/com/usanew/wheretogo

 

 

I'm using a Data Group to identify the affect remote_addr, but not sure how to identify the specific URI content and replace it on the fly.

    Hi Kevin,

    You can rewrite the URI with HTTP::uri and the path with HTTP::path. Here is an example: 

     
 when HTTP_REQUEST { 
  
      Datagroup check loigic goes here 
    ... 
  
     Check if path starts with /com/usa/ 
    if {[HTTP::path] starts_with "/com/usa/"}{ 
  
        Replace /com/usa/ with /com/usanew/ in the path 
       HTTP::path [string map {/com/usa/ /com/usanew/} [HTTP::path]] 
    } 
 }

    Thanks for the info...adding to the question...

     

     

    What if you also wanted to add a redirect into the situation?

     

     

    Example:

     

     

    redirect http://abc.com to http://xyz.com and also change the path as noted above.

     

     

    -Thanks!

    You can change HTTP::path to HTTP::redirect. You're supposed to use a fully qualified URL in a redirect, but all browsers support a local one (URI without a protocol or domain name).
