!precondition
Allows the specification of a precondition, which must be a C++ expression
valid in the context of the request handler. This can be used to implement
authentication.
Example:
<%@ page
class="AuthSamplePage"
precondition="checkCredentials(request, response)"
%>
<%!
bool checkCredentials(Poco::Net::HTTPServerRequest& request, Poco::Net::HTTPServerResponse& response)
{
bool isAuthenticated = false;
