TUrlManager is the base class for managing URLs that can be
recognized by PRADO applications. It provides the default implementation
for parsing and constructing URLs.
Derived classes may override {@link constructUrl} and {@link parseUrl}
to provide customized URL schemes.
By default, {@link THttpRequest} uses TUrlManager as its URL manager.
If you want to use your customized URL manager, load your manager class
as an application module and set {@link THttpRequest::setUrlManager THttpRequest.UrlManager}
with the ID of your URL manager module.
