unexpected redirection

Hi Everyone


this the network topology


Client ( -----> F5 ASM ( -----> Backend Server (


F5 is performing port translation and applying web security policy


When client connect to "" it's working successfully, then press on a button called "start DRN Client" to download java file to open the application , URL is changed to "" and timed-out because we allow only inbound traffic for


i want to understand the issue and how to fix using F5

  • Hi,

    The VS port and address translation act only on network layer, while html content is at application layer.

    So you may need to rewrite the html content to proxy the explicit internal links.

    One option is by using a stream profile to rewrite that content.


    when HTTP_REQUEST {
        HTTP::header remove "Accept-Encoding"
    when HTTP_RESPONSE {
        if { [HTTP::header Content-Type] contains "text" } {
            STREAM::expression {@}

    On server side:

    <a href="">start DRN Client</a>

    On client side:

    <a href="/DRNClient/DrNClient.jnlp">start DRN Client</a>
