Key_Master's solution is a good one, but only if you're aware of the following restrictions:

[httpd.apache.org...]

(especially the one requiring Apache 1.3.13 or later to add this to a ".htaccess" file at the top of the directory tree you wish to protect, otherwise it has to be used within apache's config file.)
