WWW – Useful hints

Ask all questions and report problems to admins@utf.mff.cuni.cz.
When a client claims a directory, following files are searched (in this order): index.html, index.htm, index.php, index.cgi, default.htm, default.html. If none of these files is found, directory index is displayed (if you don't want this, put an empty index.html file in the directory). If you intend to use alternatively named file as the default, you can make a redirection in the .htaccess. However, it's a good idea to name all directory indexes index.html.
The http server is case-sensitive, so make sure that all links are correct.
The server expects all documents in Windows-1250 encoding. To change this read the mod_czech documentation or ask admins.
