The server then proceeds to make the connection on behalf of the client. Once the connection has been established by the server, the proxy server continues to proxy the TCP stream to and from the client. Only the initial connection request is HTTP - after that, the server simply proxies the established TCP connection.
Also a race condition can occur where the client sends a request to the server at the same time that the server closes the TCP connection. [15] A server should send a 408 Request Timeout status code to the client immediately before closing the connection. When a client receives the 408 status code, after having sent the request, it may open a ...
A SPICE client connection to a remote desktop server consists of multiple data channels, each of which is run over a separate TCP or UNIX socket connection.A data channel can be designated to operate in either clear-text, or TLS modes, allowing the administrator to trade off the security level vs performance.
HTTP is a stateless application-level protocol and it requires a reliable network transport connection to exchange data between client and server. [20] In HTTP implementations, TCP/IP connections are used using well-known ports (typically port 80 if the connection is unencrypted or port 443 if the connection is encrypted, see also List of TCP ...
Direct Client-to-Client (DCC) (originally Direct Client Connection [1] [2] [3]) is an IRC-related sub-protocol enabling peers to interconnect using an IRC server for handshaking in order to exchange files or perform non-relayed chats. Once established, a typical DCC session runs independently from the IRC server.
Whereas the words server and client may refer either to a computer or to a computer program, server-host and client-host always refer to computers. The host is a versatile, multifunction computer; clients and servers are just programs that run on a host. In the client–server model, a server is more likely to be devoted to the task of serving.
Tells all caching mechanisms from server to client whether they may cache this object. It is measured in seconds: Cache-Control: max-age=3600: Permanent RFC 9111: Connection: Control options for the current connection and list of hop-by-hop response fields. [13] Must not be used with HTTP/2. [14] Connection: close: Permanent RFC 9110: Content ...
Server-Sent Events (SSE) is a server push technology enabling a client to receive automatic updates from a server via an HTTP connection, and describes how servers can initiate data transmission towards clients once an initial client connection has been established. They are commonly used to send message updates or continuous data streams to a ...
