Today at school we finally fixed a nit that had been bothering me since about the time I arrived. For historical reasons our college mail server holds the A record for the college domain name. For that reason, attempts to access http://ccs.neu.edu instead of http://www.ccs.neu.edu ended up displaying an error page.
Since the primary purpose of the server in question is to handle e-mail, no webserver was installed. After stumbling upon http://aleksandarsavic.com/nginx-redirect-wwwexamplecom-requests-to-examplecom-or-vice-versa/ I whipped up a 6 line config for nginx, and deployed it on the machine. nginx is lightweight enough to be installed specifically for this purpose without making a drastic impact on the machines other tasks.
Here is our config:
## Redirector for ccs.neu.edu
server {
listen 80;
server_name ccs.neu.edu;
access_log /var/log/nginx/access.log;
rewrite ^(.*) http://www.ccs.neu.edu$1 permanent;
}
