RequirePermissions

Phase:
CHECKACCESS

Returns:
PIAPI_ERROR if this handler was invoked for an inappropriate phase, otherwise PIAPI_COMPLETED is returned. If the resource does not have the required permissions this handler sets the response status to 403 Forbidden.

Note:
Not all permission flags may be checked on all operating systems, where a permission cannot be verified because the operating system does not support the flag that permission will be considered passed. An observation of this note is that a later phase may fail to access a resource that passed this verification for the access attempted.

Example:

	<Object>
		Name AccessByFile
		Class AccessByFileClass
	</Object>

	<Object>

Action

Phase:
MAPPING

Returns:
PIAPI_ERROR if this handler was invoked for an inappropriate phase, otherwise, PIAPI_COMPLETED if a path was mapped and PIAPI_CONTINUE if no path was mapped.

Note:
The 'From' pattern must begin and end with '/' character, otherwise an initialization error will be raised. This is to ensure that path mapping does not result in unintended files becoming visible.

Note that paths are mapped in the order listed in the configuration file, so a path mapping statement with From="/" would match before one with From="/icons/" is listed first. Path mapping should be list in reverse order of directory depth to ensure correct mapping (place mapper with From="/" AFTER the one with From="/icons/").

Example:

	<Object>
		Name PathMapper
		Class PathMapperClass
	</Object>

	<Object>
		...
		CheckAccess PathMapper From="/" To="/home/Pi3Web/WebRoot/"

• The client protocol is HTTP/1.1 and the 'Connection: Close' header variable-value pair exists.

Phase:

Methods

The action caused by the HTTP methods are

Method	Action
GET	To send the requested file to the browser.
HEAD	To send only the HTTP header for the requested file to the browser.
PUT	HTTP/1.1 request, to upload the requested file from a web browser to the server. If the file already exists it must be a writeable and a regular file.
DELETE	HTTP/1.1 request, to delete the requested file. File must exist and be a regular file or directory. Deletion works not recursive in directories and directory must be empty.
POST	To upload a file using HTTP form upload with multipart message. An upload form looks like <HTML> <BODY> <FORM method="POST" enctype="multipart/form-data" action="/errors/success.htm"> <P>File <INPUT type=file name=upfile> <P>Notes <INPUT type=text name=notes> <P> <INPUT type=submit value=Upload> </FORM> </BODY> </HTML> You can use PathInfo to redirect file to an upload directory action="/errors/success.htm". The file in the action URL should always expire. Your browser will force this with a meta tag in the HTML-Header <META http-equiv="expires" content="0">
OPTIONS	HTTP/1.1 request, to retrieve the supported methods for the respective URL or the server itself.
TRACE	HTTP/1.1 request, which works like an echo handler. this could be used to test the client
