## 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
