When the server finds an .htaccess file (as specified by AccessFileName), it needs to know which directives declared in that file can override earlier configuration directives.

AllowOverride is valid only in <Directory> sections specified without regular expressions, not in <Location>, <DirectoryMatch> or <Files> sections.

When this directive is set to None and AllowOverrideList is set to None, .htaccess files are completely ignored. In this case, the server will not even attempt to read .htaccess files in the filesystem.

When this directive is set to All, then any directive which has the .htaccess Context is allowed in .htaccess files.



if AllowOverride is missing or set to None, .htaccess will not work

if AllowOverride is set to All, all directives in .htaccess will work
