1ac39787115a288f5e848344b1b1e8dccb1c58f1nd <p><code>.htaccess</code> files provide a way to make configuration
1ac39787115a288f5e848344b1b1e8dccb1c58f1nd changes on a per-directory basis. A file, containing one or more
63f06dce77bb2d9b1c5aa5deeb47a1069987fd1end configuration directives, is placed in a particular document directory,
63f06dce77bb2d9b1c5aa5deeb47a1069987fd1end and the directives apply to that directory, and all subdirectories thereof.</p>

63f06dce77bb2d9b1c5aa5deeb47a1069987fd1end <p>SSI (Server Side Includes) are directives that are placed in
63f06dce77bb2d9b1c5aa5deeb47a1069987fd1end HTML pages, and evaluated on the server while the pages are
63f06dce77bb2d9b1c5aa5deeb47a1069987fd1end being served. They let you add dynamically generated content to
