Detailed Description

This class represents application's mount point or the rule on which specific application is selected to process the query.

It is used by applications_pool class for mounting applications, and by forwarding managers to match forwarding requests

Member Enumeration Documentation

enum cppcms::mount_point::selection_type

Type that describes what parameter should be passed to application::main(std::string) function

When the application selected specific string is passed for matching with application's member function or application's children. This can be CGI variable PATH_INFO or SCRIPT_NAME or their substring taken with regular expression.

If selection is match_path_info then PATH_INFO passed for matching, otherwide SCRIPT_NAME is used for matching.

For example if your service works with SCRIPT_NAME /app and the URL is pointing to /app/page/20 such as SCRIPT_NAME is "/app" and PATH_INFO is "/page/20" then the last one will be used for dispatching by cppcms::application::main function.

But you may also work with "*.cgi" style URL if your application process all queries comping from "*.cgi" and you have "dummy scripts" at "/cgi-bin/users.cgi" and "/cgi-bin/app.cgi" and you want to match against SCRIPT_NAME rather then PATH_INFO you can use match_script_name option and the script name will be used for matching.

Enumerator:

match_path_info	Pass PATH_INFO to applications.
match_script_name	Pass SCRIPT_NAME to applications.

Constructor & Destructor Documentation

cppcms::mount_point::mount_point ( )

Create default mount point, it uses PATH_INFO for url-dispatching and gives no restriction on URL

cppcms::mount_point::~mount_point ( )

Destructor

cppcms::mount_point::mount_point ( mount_point const & )

Copy constructor

cppcms::mount_point::mount_point	(	std::string const &	path,
		int	group
	)

Create a mount point that checks PATH_INFO only and passes matched group for dispatching

cppcms::mount_point::mount_point ( std::string const & script )

Create a mount point that checks SCRIPT_NAME, and passes PATH_INFO for dispatching

cppcms::mount_point::mount_point	(	std::string const &	script,
		std::string const &	path,
		int	group
	)

Create a mount point that checks SCRIPT_NAME, PATH_INFO only and passes matched PATH_INFO's group for dispatching

cppcms::mount_point::mount_point	(	selection_type	sel,
		std::string const &	selected_part,
		int	group
	)

Create a mount point with selection rule sel.

Parameters:

sel	selection rule use SCRIPT_INFO or PATH_NAME for URL based dispatching
selected_part	is a regular expression for matching against PATH_INFO or SCRIPT_NAME according sel
group	regular expression subgroup of selected_part for URL dispatching

cppcms::mount_point::mount_point	(	selection_type	sel,
		std::string const &	non_selected_part
	)

Create a mount point with selection rule sel.

Parameters:

sel	-- selection rule use SCRIPT_INFO or PATH_NAME for URL based dispatching
non_selected_part	is a regular expression for matching against PATH_INFO or SCRIPT_NAME according to opposite of sel, if sel is match_path_info then non_selected_part checked against SCRIPT_NAME otherwise it is checked against PATH_INFO

cppcms::mount_point::mount_point	(	selection_type	sel,
		std::string const &	non_selected_part,
		std::string const &	selected_part,
		int	group
	)

Create a mount point with selection rule sel.

Parameters:

sel	-- selection rule use SCRIPT_INFO or PATH_NAME for URL based dispatching
non_selected_part	is a regular expression for matching against PATH_INFO or SCRIPT_NAME according to opposite of sel, if sel is match_path_info then non_selected_part checked against SCRIPT_NAME otherwise it is checked against PATH_INFO
selected_part	is a regular expression for matching against PATH_INFO or SCRIPT_NAME according sel
group	regular expression subgroup of selected_part for URL dispatching

cppcms::mount_point::mount_point	(	selection_type	sel,
		booster::regex const &	http_host,
		booster::regex const &	script,
		booster::regex const &	path,
		int	group
	)

Create fully defined mount rule for matching against, http_host - HTTP_HOST, script - SCRIPT_NAME, path - PATH_INFO, and use subgroup group of regular expression selected with sel definition.

Note: if regular expression is empty, no checks are performed.
