URL rewrite

Hi all,

 

 

I have a question on URL re-write,

 

 

can I use i-Rules to re-write the following URL like? if yes, is it the same meaning as redirect? coz after rewrite the URL, http request should be redirected to the mentioned rewrite URL, am I right?

 

 

 

Example:

 

http://www.f5.com ----> VIP ---> http://www.yahoo.com/search?q=www.f5.com

 

 

 

For iRules, how can I archieve this?

 

Thanks a lot

    Hi Abeny,

    A redirect will result in a 301 or 302 status response being sent to the client with a Location header value that indicates to the client where to make a new GET request. The browser address bar will update to show the change in the URL to the Location header value. Rewriting the host and/or URI will be transparent to the client--the change is made before the request is sent to the pool member.

    Here is an example of a redirect: 

     
 when HTTP_REQUEST { 
  
     Redirect all requests to http://www.yahoo.com/search?q=$host 
     where $host is the originally requested hostname 
    HTTP::respond 302 noserver Location "http://www.yahoo.com/search?q=[HTTP::host]" 
 }

    And an example for rewriting the host header and URI: 

     
 when HTTP_REQUEST { 
  
     Rewrite the hsot header to www.yahoo.com and the  
     uri to /search?q=$host where $host is the originally requested hostname 
    HTTP::header replace "www.yahoo.com" 
    HTTP::uri "/search?q=[HTTP::host]" 
 }
