Hiding the port number on SchoolBell using mod_rewrite

I've just set up the Shuttleworth Foundation's slick little calendar server, SchoolBell. It runs on port 7180 by default, but I didn't want to my colleagues (that's what you call everyone else if you work at a school) to have to remember that. Digging around in the README file for a related program, SchoolTool, I found a suggestion that mod_rewrite would help me out. In the end, this worked on Ubuntu 5.10, Breezy Badger:

    ServerName calendar.chewonki.org
    RewriteEngine On
    RewriteRule ^/(.*) http://calendar.chewonki.org:7180

Note that I'm mapping most of our hosts (like "calendar") using our internal DNS server, so all you wandering internet folks can't resolve the URLs above. I also had to enable the mod_rewrite module with the a2enmod command.

We'll see how SchoolBell works. I suspect we'll have 15 excited users, 10 people who think it's a pain in the ass to use computers for calendaring, and everyone else (from the set of all colleagues) won't even know it exists.

*Update: I just upgraded Breezy to use SchoolBell 1.2.2 from 1.2.1. The performance difference is shocking. From my little bit of experimenting, it's 5-10 times faster. The slowest task was viewing a whole year at once. It previously took 15-20 seconds to load; now it's 2-3 seconds, and the server is still configuring packages to complete the update, and the server sucks. Well done and thank you, Tom Hoffman, Mark Shuttleworth, and co.*
