Questions tagged [http-1.1]

HTTP 1.1 is the latest version of the http protocol. It includes more stringent requirements than HTTP/1.0 in order to ensure reliable implementation of its features.

The Hypertext Transfer Protocol (http) is an application-level protocol for distributed, collaborative, hypermedia information systems. HTTP has been in use by the World-Wide Web global information initiative since 1990.

HTTP/1.0 does not sufficiently take into consideration the effects of hierarchical proxies, caching, the need for persistent connections, or virtual hosts. In addition, the proliferation of incompletely-implemented applications calling themselves "HTTP/1.0" has necessitated a protocol version change in order for two communicating applications to determine each other's true capabilities.

The new version of the protocol (HTTP 1.1) includes more stringent requirements than HTTP/1.0 in order to ensure reliable implementation of its features.

Here are some of the new features introduced with HTTP 1.1:

Host field: HTTP 1.1 has a required Host header by spec.
Persistent connections: HTTP 1.1 also allows you to have persistent connections which means that you can have more than one request/response on the same HTTP connection.
OPTIONS method: HTTP/1.1 introduces the OPTIONS method. An HTTP client can use this method to determine the abilities of the HTTP server. It's mostly used for Cross Origin Resource Sharing in web applications.
Caching: HTTP 1.1 expands on the caching support a lot by using something called 'entity tag'. If 2 resources are the same, then they will have the same entity tags.
HTTP 1.1 also adds the If-Unmodified-Since, If-Match, If-None-Match conditional headers.
100 Continue status: there is a new return code in HTTP/1.1 100 Continue. This is to prevent a client from sending a large request when that client is not even sure if the server can process the request, or is authorized to process the request. In this case the client sends only the headers, and the server will tell the client 100 Continue, go ahead with the body.
Digest authentication and proxy authentication
Extra new status codes
Chunked transfer encoding
Connection header
Enhanced compression support
