NAME ^

Net::HTTPServer::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 ^
