Abstract: A provider computer announces content to the provider computer and establishes a secure connection to a VPN server. Requests for the content are received in one protocol (HTTPS) from the consumer computer and forwarded to the VPN server in a less secure protocol (HTTP) by a protocol conversion proxy, which then forwards the request to the provider computer. A public URL and secure URL may be associated with the same content. The public URL is announced to a consumer computer. A public server receives the public URL and returns the secure URL, which consumer computer uses to establish a secure connection to the provider computer. Upon the secure URL being compromised, a new secure URL is associated with the public URL. The source IP addresses of requests for the public and secure URLs may be compared to determine whether the secure URL is compromised.
