I have a few question about request filtering. Using the standard filters that come pre-configured is nice however, I think a bit of explanation about what each does would be nice for newbies, etc... On our site, we allow people to customize their profiles like MySpace using CSS. However, with the pre-configured rules, it blocks them from doing so. If I knew what each regular expression did, I could adjust it correctly. More detailed info would be nice as well as how to construct our own filters. Thanks in advance.
