The question mark (?) is messing you up here, because it has special connotations in a regular expression (so do periods (.) but they would not prevent this RE from working). Use this instead: awprofessional\.com/articles/article\.asp\?p=363731 and you should find that the article is blocked. As has been stated before, use dstdomian whenever possible, as regular expression matching is computationally demanding. In any case, there is a nice regular expression tutorial at http://www.regular-expressions.info/tutorial.html Chris
