The WebSocket protocol is implemented in different web browsers, web servers, and run-time environments and libraries acting as clients or servers. The following is a table of different features of notable WebSocket implementations.
The client sends an HTTP request (method GET, version ≥ 1.1) and the server returns an HTTP response with status code 101 (Switching Protocols) on success.This means a WebSocket server can use the same port as HTTP (80) and HTTPS (443) because the handshake is compatible with HTTP.
However, the default connection timeout of Apache httpd 1.3 and 2.0 is as little as 15 seconds [6] [7] and just 5 seconds for Apache httpd 2.2 and above. [8] [9] The advantage of a short timeout is the ability to deliver multiple components of a web page quickly while not consuming resources to run multiple server processes or threads for too ...
The first change is to greatly reduce overhead during connection setup. As most HTTP connections will demand TLS, QUIC makes the exchange of setup keys and listing of supported protocols part of the initial handshake process. When a client opens a connection, the response packet includes the data needed for future packets to use encryption.
The WebSocket Protocol has two parts: a handshake to establish the upgraded connection, then the actual data transfer. First, a client requests a WebSocket connection by using the Upgrade: WebSocket and Connection: Upgrade headers, along with a few protocol-specific headers to establish the version being used and set up a handshake.
An intermediary machine or process rejected the call attempt. [25] This contrasts with the 607 (Unwanted) SIP response code in which a human, the called party, rejected the call. The intermediary rejecting the call should include a Call-Info header with "purpose" value "jwscard", with the jCard [26] with contact details. The calling party can ...
Apple has also ported WebKit to iOS to run on the iPhone, iPod Touch, and iPad, where it is used to render content in the device's web browser and e-mail software. [58] The Android mobile phone platform used WebKit (and later versions its Blink fork ) as the basis of its web browser [ 59 ] [ 60 ] [ 61 ] and the Palm Pre , announced January 2009 ...
[12] [13] In October 2011, the W3C published its first draft for the spec. [14] WebRTC milestones include the first cross-browser video call (February 2013), first cross-browser data transfers (February 2014), and as of July 2014 Google Hangouts was "kind of" using WebRTC. [15] The W3C draft API was based on preliminary work done in the WHATWG ...
