Apache websever configuration

In configuring Apache to allow various directives in an .htaccess file, if you find yourself banging your head against a wall since you have used:

AllowOverride All

...and some directives still are not accepted, its because this line doesn't actually allow everything - to do that you need to use:

AllowOverride AuthConfig FileInfo Indexes Limit Options=All,MultiViews

Obviously the more things you allow, the less secure your server...
