+ 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]/. + +
