Port and URL redirection with SSL Client Side offloading

Here is a statement that incorporates some of the things you mention. I hope it helps. If you require further help you need to state your requirements clearly.

when HTTP_REQUEST {
    HTTP::respond 302 Location "http://[HTTP::host]:82/[HTTP::path]/xyz"
}

When you say "I want to add port 82 to the standard rediection scripts aren't working. Would also like to hiding the port after the redirection takes place". If you issue an HTTP redirect then the redirected location WILL be present in the client browser - that cannot be hidden.
