The Options directive controls which server features are available in a particular directory.
option can be set to None, in which case none of the extra features are enabled, or one or more of the following:
All- All options except for
MultiViews. This is the default setting. ExecCGI- Execution of CGI scripts using
mod_cgiis permitted. FollowSymLinks- The server will follow symbolic links in this directory.
Even though the server follows the symlink it does not change the pathname used to match against
<Directory>sections.Note also, that this option gets ignored if set inside a
<Location>Omitting this option should not be considered a security restriction, since symlink testing is subject to race conditions that make it circumventable.
Includes- Server-side includes provided by
mod_includeare permitted. IncludesNOEXEC- Server-side includes are permitted, but the
#exec cmdand
#exec cgi#include virtualCGI scripts fromScriptAliased directories. Indexes- If a URL which maps to a directory is requested, and there is no
DirectoryIndexindex.html) in that directory, then
mod_autoindexwill return a formatted listing of the directory. MultiViews- Content negotiated “MultiViews” are allowed using
mod_negotiation. SymLinksIfOwnerMatch- The server will only follow symbolic links for which the target file or directory is owned by the same user id as the link.
Note
This option gets ignored if set inside a
<Location>section.This option should not be considered a security restriction, since symlink testing is subject to race conditions that make it circumventable.
Normally, if multiple Options could apply to a directory, then the most specific one is used and others are ignored; the options are not merged. (Seehow sections
are merged.) However ifall the options on the
Options+ or - symbol, the options are merged. Any options preceded by a+ are added to the options currently in force, and any options preceded by a- are removed from the
options currently in force.
Warning
Mixing Options with a + or - with those without is not valid syntax, and is likely to cause unexpected results.
For example, without any + and - symbols:
<Directory /web/docs>
Options Indexes FollowSymLinks
</Directory>
<Directory /web/docs/spec>
Options Includes
</Directory>
then only Includes will be set for the /web/docs/spec directory. However if the secondOptions directive uses the
+ and - symbols:
<Directory /web/docs>
Options Indexes FollowSymLinks
</Directory>
<Directory /web/docs/spec>
Options +Includes -Indexes
</Directory>
then the options FollowSymLinks and Includes are set for the/web/docs/spec directory.
Note
Using -IncludesNOEXEC or -Includes disables server-side includes completely regardless of the previous setting.
The default in the absence of any other settings is All.
