How do I .htaccess put another file, other than index.php , as primary, that is, put a file named home.php and make it work as if it were a index.php .
I'd also like to know some defensive configurations that it allows you to do over directories.
To change index.php to another file home.php use this line in your .htaccess
DirectoryIndex home.php
But if you want all hits to point to home.php , 2 lines are enough on your .htaccess :
RewriteEngine on
RewriteRule . home.php [L]
And to not list the files in a directory, add this line at the beginning of .htaccess :
Options -Indexes
