IfModule Conditions

List of modules which must be loaded to use directive configuration.

yes

IfModules

Order

The Order directive, along with the Allow and Deny directives, controls a three-pass access control system. The first pass processes either all Allow or all Deny directives, as specified by the Order directive. The second pass parses the rest of the directives (Deny or Allow). The third pass applies to all requests which do not match either of the first two.

no

Order

Allow

The Allow directive affects which hosts can access an area of the server. Access can be controlled by hostname, IP address, IP address range.
The environment variables settings are not supported in the user interface.

no

Allow

Deny

The arguments for the Deny directive are identical to the arguments for the Allow directive.

no

Deny

Allow Override

no

AllowOverride

Add Default Charset

This directive specifies a default value for the media type charset parameter (the name of a character encoding) to be added to a response if and only if the response's content-type is either text/plain or text/html.
Value "Off" disables this functionality. "On" enables a default charset of iso-8859-1. Any other value is assumed to be the charset to be used, which should be one of the IANA registered charset values for use in MIME media types.

no

AddDefaultCharset

Default Type

There will be times when the server is asked to provide a document whose type cannot be determined by its MIME types mappings.
The server SHOULD inform the client of the content-type of the document. If the server is unable to determine this by normal means, it will set it to the configured DefaultType.

no

DefaultType

Directory Index

Sets the list of resources to look for, when the client requests an index of the directory by specifying a / at the end of the directory name.
Note that the documents do not need to be relative to the directory.

no

DirectoryIndex

Error Document

In the event of a problem or error, Apache can be configured to do one of four things,
1. output a simple hardcoded error message,
2. output a customized message,
3. redirect to a local URL-path to handle the problem/error,
4. redirect to an external URL to handle the problem/error.
The first option is the default, while options 2-4 are configured using the ErrorDocument directive, which is followed by the HTTP response code and a URL or a message. Apache will sometimes offer additional information regarding the problem/error.

yes

ErrorDocument

Options

The Options directive controls which server features are available in a particular directory.

no

Options

Use Canonical Name

With UseCanonicalName On Apache will use the hostname and port specified in the ServerName directive to construct the canonical name for the server. This name is used in all self-referential URLs, and for the values of SERVER_NAME and SERVER_PORT in CGIs.
With UseCanonicalName Off Apache will form self-referential URLs using the hostname and port supplied by the client if any are supplied (otherwise it will use the canonical name, as defined above).
UseCanonicalName DNS is intended for use with mass IP-based virtual hosting to support ancient clients that do not provide a Host: header. With this option Apache does a reverse DNS lookup on the server IP address that the client connected to in order to work out self-referential URLs.

no

UseCanonicalName

Use Canonical Physical Port

In many situations Apache must construct a self-referential URL -- that is, a URL that refers back to the same server. With UseCanonicalPhysicalPort On Apache will, when constructing the canonical port for the server to honor the UseCanonicalName directive, provide the actual physical port number being used by this request as a potential port. With UseCanonicalPhysicalPort Off Apache will not ever use the actual physical port number, instead relying on all configured information to construct a valid port number.

no
