To offer secure transactions on your web site, such as credit card purchases, you will want to link a Secure Virtual Server to your Virtual Server. A Secure Virtual Server provides SSL encryption for a site. Servlets.Net provides this service using the industry standard Apache 1.3 web server with SSL support. All content that travels between a Secure Virtual Server and your visitors' web browsers is safely encrypted. Your Secure Virtual Server is associated with one of your Virtual servers, and it requires a registered digital certificate from a third party vendor, such as Thawte or VeriSign.
