How to rewrite HTTP payload using Irule

Hello Team,

 

I have simple requirement that i need to rewrite HTTP payload whenever a request if genrated for opening a document.

 

For ex:- The below link and chracter which is made bold shoudl be replaced when request land on server https://abc.com/xyz/123xcv/1401300147/InfoView/listing/main.do?service=/common/appService.do&appKind=InfoView&isNewWindow=true&newUrl=https%3A%2F%2Fabc.com%2Fxyz%2F123xcv%

 

I need to replace the trailing https%3A%2F%2Fabc.com% with http://xyz.com:8080/...

 

I tried above with stream profile but not able to get any sucess..

 

Helpful if someone can put light on the above rewriting..

 

Regards Siddhesh

    Is this URL in the browser address bar, or actually in the HTTP payload? If the latter, request or response?

    Well, just a hunch here, but guessing you could accomplish this with a stream iRule. Apply a blank stream profile to the VIP and this iRule:

     

    when HTTP_REQUEST {    
     disable server side compression         
    HTTP::header remove Accept-Encoding        

     disable stream for requests         
    STREAM::disable
}    
when HTTP_RESPONSE {    
     only do this for text-based responses        
    if { [HTTP::header Content-Type] contains "text" } {        
         establish the stream expression             
        STREAM::expression {@https%3A%2F%2Fabc.com@http://xyz.com:8080@}

         enable stream processing            
        STREAM::enable
    }
}

     

    You may actually need to do this:

     

    {@https%3A%2F%2Fabc.com@http%3A%2F%2Fxyz.com%3A8080@}
