Hullo

I uninstalled isapi and reinstalled the whole IIS7 through adding roles.
I have now installed ARR V2 on the windows server 2008 rackspace cloud server (32 bit AMD). I would like setup ARR up with tomcat so that my application located at c:\tomcat\webapps\track can run. Tomcat is running on port 8080.

I have read around on how this can be done starting from proxy config, url rewrite, server farms etc, but i find everything confusing.
I humbly request that you write for me the how i can do this using the details below. It has taken me over a week trying to get this application run.
my cloud server/computer name: trackafrica
IP: 173.203.226.218
domain: trackafrica.com
I would like the application to run at: http://trackafrica.com:8080/track
I have tried the following but its failing to display:
condition: {HTTP_HOST} == to match trackafrica.com
rewrite url to: http://trackafrica.com:8080/{R:1}
I will be very glad to receive a response on this
Regards
