URI transformation

I would like to have iRule select a pool and transform the URI similar to shown below:

Client enters:

    https://www.test.com/alpha

For communication between LTM and server, I need the URI to be transformed several directories down:

    https://nodeip/random/deep/level/directory/structure

So, final result is the client only sees https://www.test.com/alpha, but the entire URI /random/deep/level/directory/structure is sent to the node.

    Hello,

     

    You can use an irule to translate the client URI to the server using the following command : HTTP::uri

     

    You can also use an LTM policy to do the job

    Hi Dale,

    Make sure you apply Stream profile on VIP before applying below iRule.

            when HTTP_REQUEST {
        HTTP::header remove Accept-Encoding
        STREAM::disable
            }
        when HTTP_RESPONSE {
         Disable the stream filter for server responses
        STREAM::disable
         Enable the stream filter for text responses only
        if {[HTTP::header value Content-Type] contains "text"}{
        Replace 'old_text' with 'new_text'
       STREAM::expression {@https://nodeip/random/deep/level/directory/structure@https://www.test.com/alpha@}
         Enable the stream filter for this response only
        STREAM::enable
            }
        }
