An expansion of the 400 Bad Request response code, used when a client certificate is required but not provided. 497 HTTP Request Sent to HTTPS Port. An expansion of the 400 Bad Request response code, used when the client has made a HTTP request to a port listening for HTTPS requests. 499 Client Closed Request.
RFC (s) RFC 9293. The Transmission Control Protocol ( TCP) is one of the main protocols of the Internet protocol suite. It originated in the initial network implementation in which it complemented the Internet Protocol (IP). Therefore, the entire suite is commonly referred to as TCP/IP. TCP provides reliable, ordered, and error-checked delivery ...
Explicit Congestion Notification ( ECN) is an extension to the Internet Protocol and to the Transmission Control Protocol and is defined in RFC 3168 (2001). ECN allows end-to-end notification of network congestion without dropping packets. ECN is an optional feature that may be used between two ECN-enabled endpoints when the underlying network ...

Transmission Control Protocol (TCP) uses a congestion control algorithm that includes various aspects of an additive increase/multiplicative decrease (AIMD) scheme, along with other schemes including slow start [1] and congestion window (CWND), to achieve congestion avoidance. The TCP congestion-avoidance algorithm is the primary basis for ...

The HTTP persistent connections do not use separate keepalive messages, they just allow multiple requests to use a single connection. However, the default connection timeout of Apache httpd 1.3 and 2.0 is as little as 15 seconds and just 5 seconds for Apache httpd 2.2 and above.
HTTP ( Hypertext Transfer Protocol) is an application layer protocol in the Internet protocol suite model for distributed, collaborative, hypermedia information systems. [1] HTTP is the foundation of data communication for the World Wide Web, where hypertext documents include hyperlinks to other resources that the user can easily access, for ...

The TCP_QUICKACK flag is available on Linux since 2001 (2.4.4) and potentially on Windows, where the official interface is SIO_TCP_SET_ACK_FREQUENCY. Setting TcpAckFrequency to 1 in the Windows registry turns off delayed ACK by default. On FreeBSD, the sysctl entry net.inet.tcp.delayed_ack controls the default behavior.
e. TCP tuning techniques adjust the network congestion avoidance parameters of Transmission Control Protocol (TCP) connections over high- bandwidth, high- latency networks. Well-tuned networks can perform up to 10 times faster in some cases. [1] However, blindly following instructions without understanding their real consequences can hurt ...
