Tally of cycle types in a permutation group

Anyone good with GAP? I've defined a largish permutation group and would like to make a tally of elements by cycle type - how many of each cycle type occurs in the group. Possible? Trivial? Use something else instead? Oh, and where's the right place to ask GAP questions?

How do I force HTTPS in Tomcat (through Apache and mod_jk)?

I'm at my wit's end. I've been trying to configure tomcat (through apache 2 using mod_jk) to automatically re-direct all traffic to HTTPS from HTTP. More boring technical details to follow. Specifically, I'm trying to get CAS working. Tomcat is successfully serving-up the pages over HTTP and HTTPS and the application is working as expected. However, since this particular servlet handles user authentication I would like Tomcat to force HTTPS for all requests.

I have tried using isSecure() through JSP to redirect users but it simply puts the requests into an endless loop. I have tried the following configuration in the web.xml file (see Lukas Bradleys' answer) and it does force a redirect, but it uses the server hostname as the URL and not the proxied URL to the server (which means it doesn't work externally).

I've tried changing the hostname on the server but it continues to use the initial hostname which leads me to believe that this value is somewhere in the Tomcat configuration, but I cannot locate it.

So, is there an easier way to do this? Or, does anyone know where to look to modify that hostname to use the URL for the proxied site? Any assistance would be appreciated.
