Error 404--Not Found

Error 404--Not Found

From RFC 2068 Hypertext Transfer Protocol -- HTTP/1.1:

10.4.5 404 Not Found

The server has not found anything matching the Request-URI. No indication is given of whether the condition is temporary or permanent.

If the server does not wish to make this information available to the client, the status code 403 (Forbidden) can be used instead. The 410 (Gone) status code SHOULD be used if the server knows, through some internally configurable mechanism, that an old resource is permanently unavailable and has no forwarding address.

TLS (Transport Layer Security)

An IETF-sponsored protocol intended to secure and authenticate communications across a public network through data encryption. It is designed as a successor to SSL.

The protocol consists of two layers - a TLS Handshake Protocol and, below that, a TLS Record Protocol. The handshake protocol creates a "secret" used by the record protocol to encrypt messages. The record protocol also provides mechanisms for preventing a message from being altered.

The overall protocol is designed to be application independent, so that application or higher-level protocol developers can choose the best way for initiating TLS handshaking and interpreting authentication certificates.
