I've been using Apache Web Server for some basic sites, but I'm starting to want to do interesting things with the configuration. And by interesting I mean that I have come to hate the documentation.

Anyone know if it's possible to do a course on this kind of thing? Or even know of a good online equivelent?

I've done dozens of tech course over the years, can't say any were of much value. Spending $4000 for a weeks training normally only covers that basics. My advice is find a recommended book on amazon and submit your order. Best of Luck.
