Variant objects in the context of HTTP are objects served by an Origin Content Server in a type of transmitted data variation (i.e. uncompressed, compressed, different languages, etc.). HTTP/1.1 (1997?1999) introduces Content/Accept headers. These are used in HTTP requests and responses to state which variant the data is presented in.

Transport Layer Security (TLS) and its predecessor, Secure Sockets Layer (SSL), are cryptographic protocols designed to provide communications security over a computer network.They use X.509 certificates and hence asymmetric cryptography to authenticate the counterparty with whom they are communicating,and to negotiate a symmetric key. This session key is then used to encrypt data flowing between the parties. This allows for data/message confidentiality, and message authentication codes for message integrity and as a by-product, message authentication. Several versions of the protocols are in widespread use in applications such as web browsing, electronic mail, Internet faxing, instant messaging, and voice-over-IP (VoIP). An important property in this context is forward secrecy, so the short-term session key cannot be derived from the long-term asymmetric secret key. As a consequence of choosing X.509 certificates, certificate authorities and a public key infrastructure are necessary...

End users primarily use widgets to enhance their personal web experiences, or the web experiences of visitors to their personal sites. The use of widgets has proven increasingly popular, where users of social media are able to add stand-alone applications to blogs, profiles and community pages. Widgets add utility in the same way that an iPhone application does. The developers of these widgets are often offering them as a form of sponsored content, which can pay for the cost of the development when the widgets' utility maps to the user's needs in a way where both parties gain. For example, a sports news brand might gain awareness and increased audience share in exchange for the utility of current game scores being instantly and dynamically available - the blog which posted the Sports score widget might gain in having a stickier site. Element of control One important factor with Widgets is that the host does not control the content. The content or the functionality it provides...

When the connection starts, the record encapsulates a "control" protocol the handshake messaging protocol  (content type 22). This protocol is used to exchange all the information required by both sides for the exchange of the actual application data by TLS. It defines the messages formatting or containing this information and the order of their exchange. These may vary according to the demands of the client and server i.e., there are several possible procedures to set up the connection. This initial exchange results in a successful TLS connection (both parties ready to transfer application data with TLS) or an alert message

A suffix proxy allows a user to access web content by appending the name of the proxy server to the URL of the requested content (e.g. "en.wikipedia.org.SuffixProxy.com"). Suffix proxy servers are easier to use than regular proxy servers but they do not offer high levels of anonymity and their primary use is for bypassing web filters. However, this is rarely used due to more advanced web filters.

In name-based virtual hosting, also called shared IP hosting, the virtual hosts serve multiple host names on a single machine with a single IP address. This is possible because when a web browser requests a resource from a web server using HTTP/1.1 it includes the requested host name as part of the request. The server uses this information to determine which web site to show the user.

A shared web hosting service refers to a web hosting service where many websites reside on one web server connected to the Internet. Each site "sits" on its own partition, or section/place on the server, to keep it separate from other sites. This is generally the most economical option for hosting, as many people share the overall cost of server maintenance.
