uri rewrite rule

If anyone can provide any assistance with the following then it would be much appreciated:

 

 

I have a customer who wants an irule to rewrite the uri so that when the user connects to the virtual server, they are passed through to the backend host with a slightly different uri.

 

 

eg.

 

 

user connects to http://www.virtualserver.com/test/index.html

 

user is directed to http://www.backendhost.com/sample/test/index.html

 

 

 

Many thanks!

    So you're looking for something like this, I believe:

    
when HTTP_REQUEST {
  if{([HTTP::host] equals "virtualserver") and ([HTTP::uri] contains "test")} {
    HTTP::redirect "http://www.backendhost.com/sample[HTTP::uri]"
  }
}

    Colin,

     

     

    I don't think he is looking for a redirect... It seems he is looking for a transparent URI rewrite:

     

     

    HTTP::uri "sample[HTTP::uri]"

     

     

    Cheers,

    You can use the HTTP::uri command to change the URI passed to the backend server.

     

     

    Check out my blog post covering this one:

    Hi Don,

     

     

    Can you enable debug on the iRule and post the anonymized logs from /var/log/ltm for a request to the home page and the following references? Can you use a browser plugin like HttpFox for Firefox or Fiddler for IE to see what is wrong with the image references?
