What's getting you is called "regular expressions" aka regexp aka regex. The value of $1 is whatever matches what is in the (). You are literally telling it to set $1 to exe or dll or ida or idq. Try this: RedirectMatch ^http://[^/]+(.*\.{exe|dll|ida|idq}.*)$ http://www.microsoft.com/root.exe The first ^ means beginning of line (or beginning of string in this case). The "http://"; literally matches the string "http://";. The [^/]+ means 1 or more characters that are not a /. This should match the hostname portion (which we don't care about). The next part is where the magic happens. Everything that matches inside parenthesis will be assigned to $1. Let me go through the bits one by one: .* Match everything. By definition, it will match as much as it can and stop when the following rules match. Assuming "greedy" mode. If you have to ask, go buy the "Mastering Regular Expressions" book by O'Reilly. \. Match a literal ".". Have to escape it because the . is also a wildcard that matches any char. {exe|dll|ida|idq} Match any of those 4 letter sequences. This and the previous rule match any ".exe" or ".dll" (etc) sequence within the URL. The initial ".*" matches all characters before that starting with the first "/" character (since the http://[^/]+ matched everything up to but not including the leading /). .* Anything else is matched, such as ?user=500. $ End of line (or end of string in this case). Let me know how this works. It is completely untested and it may just break your apache logging. Test it first. Blue skies...
