- There are a couple of things you must write differently when using .htaccess instead of main configuration files. Here's a listing of (currently) only one :-)
+ There are a couple of things you must write differently when using .htaccess instead of main configuration files. Here's a listing.
+ 
+ === .htaccess location ===
+ When you enable .htaccess files for a certain directory, with AllowOverride, then for that directory and all subdirectories of that directory, the AllowOverride will apply.  This is probably what you expected, so nothing wrong with that.  However, when looking for a .htaccess file, apache will look for a file in the directory you access, but it will look for .htaccess files in its parents, too!
+ 
+ Examples:
+ 
+ {{{
+ <VirtualHost *:80>
+   ServerName example.com
+   DocumentRoot /var/www/example/
+ 
+   <Directory /var/www/example/>
+     AllowOverride All
+   </Directory>
+ </VirtualHost>
+ }}}
+ 
+ This will allow you to put use .htaccess files on content inside the /var/www/example/ directory (ie: on the http://example.com/ site).  This applies to /var/www/example/images/ or http://example.com/images/ too, for example.
+ 
+ On the other hand, when you access http://example.com/images/, apache will look for .htaccess files in these locations in the following order:
+  1. /var/www/example/images/.htaccess
+  1. /var/www/example/.htaccess
+  1. /var/www/.htaccess
+  1. /var/.htaccess
+  1. /.htaccess
  
  === RewriteRules ===
