Maintaining Session State in a VSP Application

VS-U-5 Basics

SSL example

Preliminaries

• The Virtuoso Web server can be set up for HTTPS listening, for increased security.
• Passing the session id as a cookie or a URL parameter over HTTP connection is not secure.

Example

This example uses the most common URL poisoning over SSL connection.

• This example repeats the example VS-U-2, but result of VSP pages is transferred over SSL.
• Make sure that files containing server certificate/key data exists in the server working directory. The following files are required for the example:
  1. virtuoso_cert.pem - server certificate
  2. virtuoso_key.pem - server private key
• The example script defines and starts a HTTPS server on port 4333.
