The instructions in the docs for later versions of Web Connection should also work for older versions... But there are a number of optimizations for later versions of the OS. You should at least update to version 4.68 which was the last 4.x version and has many improvements from your version.
Thanks for the information. It's encouraging to know that we won't have to upgrade EVERYTHING to get this to work. I don't like to "fix what ain't broke". ;-)
