Earlier in the month, I blogged about Servlet Filters and how I see them as Aspects in the AOP world. Based on the blog entry, I’ve gotten tons of email from people that wanted to know more about Servlet Filters, how to use them and how to use the simple Authentication filter I used as an example. I also got quite a few emails from people that wanted to know what other filters I used and so I am including some resources that I find very helpful along with a few servlet filters that I use every day.

Servlet Filter Tutorials

• The Essentials of Filters

If you know of any other Servlet Filters that are useful, drop me an email or send me trackback.
