net::httpserver::session

Net::HTTPServer::Session(3pm)				User Contributed Perl Documentation			     Net::HTTPServer::Session(3pm)

NAME

       Net::HTTPServer::Session - HTTP server side client session

SYNOPSIS

       Net::HTTPServer::Session handles server side client sessions

DESCRIPTION

       Net::HTTPServer::Session provides a server side data store for client specific sessions.  It uses a cookie stored on the browser to tell
       the server which session to restore to the user.  This is modelled after the PHP session concept.  The session is valid for 4 hours from
       the last time the cookie was sent.

EXAMPLES

       sub pageHandler {
	   my $request = shift;

	   my $session = $request->Session();

	   my $response = $request->Response();

	   # Logout
	   $session->Destroy() if $request->Env("logout");

	   $response->Print("<html><head><title>Hi there</title></head><body>");

	   # If the user specified a username on the URL, then save it.
	   if ($request->Env("username"))
	   {
	       $session->Set("username",$request->Env("username"));
	   }

	   # If there is a saved username, then use it.
	   if ($session->Get("username"))
	   {
	       $response->Print("Hello, ",$session->Get("username"),"!");
	   }
	   else
	   {
	       $response->Print("Hello, stranger!");
	   }

	   $response->Print("</body></html>");

	   return $response;
       }

       The above would behave as follows:

	 http://server/page		   - Hello, stranger!
	 http://server/page?username=Bob   - Hello, Bob!
	 http://server/page		   - Hello, Bob!
	 http://server/page?username=Fred  - Hello, Fred!
	 http://server/page		   - Hello, Fred!
	 http://server/page?logout=1	   - Hello, stranger!
	 http://server/page		   - Hello, stranger!

METHODS

   Delete(var)
       Delete the specified variable from the session.

   Destroy()
       Destroy the session.  The server side data is deleted and the cookie will be expired.

   Exists(var)
       Returns if the specified variable exists in the sesion.

   Get(var)
       Return the value of the specified variable from the session if it exists, undef otherwise.

   Set(var,value)
       Store the specified value (scalar or reference to any Perl data structure) in the session.
