#PARALLELS CLIENT CONNECTION SERIAL#
Close: Client sends a a FIN packet to close the TCP connection.Ī Serial HTTP connection occurs when multiple requests are issued sequentially to a server, and each request establishes a new connection.Web server sends third TCP segment with HTTP_Continue.(Client sends ACK every two segments it receives.
Web server sends second TCP segment with the PSH flag set.Load: Client loads the content of the response.Client receives the first byte of the first packet from the web server, which contains the HTTP Response headers and content. Web server processes the request, finds the resource, and sends the response to the Client.Wait: Client waits for the server to respond to the request.Send: Client sends the HTTP request to the web server.Client answers with ACK packet, concluding the three-way TCP connection establishment.Connect: Client establishes TCP connection with the IP address of.
All of the data in the HTTP protocol is expressed in human-readable ASCII text. TCP is a “connection” oriented protocol, which means when a client starts a dialogue with a server the TCP protocol will open a connection, over which the HTTP data will be reliably transferred, and when the dialogue is complete that connection should be closed. HTTP data rides above the TCP protocol, which guarantees reliability of delivery, and breaks down large data requests and responses into network-manageable chunks.
#PARALLELS CLIENT CONNECTION HOW TO#
This post describes the basics of HTTP and is the first of a series on how to diagnose performance problems. Understanding how HTTP works and what each component in an HTTP transaction means, is key to interpreting the data collected by any monitoring service. The web as we know is built on top of this protocol, which has a large impact on performance of a webpage. When dealing with web performance monitoring or optimization, it is important to learn the fundamentals of the HTTP protocol.
