+ <P>
+ Regular expressions are a way of describing a pattern - for example, "all
the words
+ that begin with the letter A" or "every 10-digit phone number" or even
"Every sentence
+ with two commas in it, and no capital letter Q". Regular expressions
(aka "regexp"s)
+ are useful in Apache because they let you apply certain attributes
against collections
+ of files or resources in very flexible ways - for example, all .gif and
.jpg files under
+ any "images" directory could be written as /.*\/images\/.*[jpg|gif]/.
+
+ <P>The best overview around is probably the one which comes with
+ Perl. We implement a simple subset of Perl's regexp support, but
+ it's still a good way to learn what they mean. You can start by
+ going to the <A
+
HREF="http://www.perl.com/CPAN-local/doc/manual/html/pod/perlre.html#Version_8_Regular_Expresions";>CPAN
+ page on regular expressions</A>, and branching out from there.
