I tried this using the information in that SOL, but it's still not working.
I don't think I explained this very well above. I'm migrating off of Microsoft ISA to the F5.
What I need to have happen is external(Internet) requests coming in as https://www.test.com/ABC123/test/test.htm need to be directed to an internal server but redirected to a different directory on that server as such. http://10.10.10.1/XYZ987/
Right now the incoming connection is trying to go to http://10.10.10.1/ABC123.test/test.htm and that directory doesn't exist.
