Options

Server Option Configuration
Syntax: Options [+|-]option [[+|-]option ...]
Example: Options +ExecCGI -MultiViews
Since: Apache 1.0

This directive controls which server features are available in a particular directory. The option argument can be None, in which case none of the extra features is enabled. Alternatively, it can have one or more of the following values:

All, for all options except MultiViews; ExecCGI, to permit the execution of CGI scripts; FollowSymLinks, to allow the server to follow symbolic links; Includes, to permit Server-Side Includes (SSI); IncludesNO==EXEC, to permit SSI but not the SSI commands ``#exec'' and ``#include''; Indexes, to enable the auto-generation of index pages if no Directory==Index file is found; MultiViews, to allow automatic content negotiation; and SymLinks==IfOwnerMatch, to allow the server to follow only the symbolic links for which the target file or directory is owned by the same user ID as the link.

Normally, if multiple Options directives could apply to a directory, then the most specific one is taken by itself; the options are not merged. If all options on the Options directive are preceded by a ``+'' or ``-'' symbol, however, they are merged. Any options preceded by a ``+'' symbol are added to the options currently in force, and any options preceded by a ``-'' symbol are removed from the options currently in force.
