Detailed Description

abstract class for HTTP request handlers anchored at a specific URL

Member Function Documentation

constructor()

HttpServer::AbstractUrlHandler::constructor	(	string	n_url_root,
		*AbstractAuthenticator	auth
	)

creates the object based on the URL root and optional authenticator

Parameters

n_url_root	the root part of the URL path without the leading "/"
auth	the authentication object to use to authenticate connections (see AbstractAuthenticator); if no AbstractAuthenticator object is passed, then by default no authentication will be required

getRelativePath()

string HttpServer::AbstractUrlHandler::getRelativePath

(

string

path

)

returns the relative path anchored from the url_root if possible

URI query arguments are stripped off, if the url_root cannot be matched then the path is returned with URI query arguments removed
