HTTP pipelining - concurrent responses per connection

阅读更多关于 HTTP pipelining - concurrent responses per connection

问题 I was just reading this Wikipedia article on HTTP pipelining and from the diagram it appears that responses can be sent concurrently on one connection. Am I misinterpreting the diagram or is this allowed? Section 8.1.2.2 of RFC 2616 states: A server MUST send its responses to those requests in the same order that the requests were received. Whilst that stops short of explicitly ruling out concurrent responses, it does not mention a need to ensure that responses must not only start in the

HTTP: what are the relations between pipelining, keep-alive and Server Sent Events?

阅读更多关于 HTTP: what are the relations between pipelining, keep-alive and Server Sent Events?

问题 I am trying to understand what are the HTTP pipelining and HTTP keep-alive connections, and trying to establish a connection between these two topics and Server Sent events technology. As far as I understand, HTTP keep-alive connection is the default in HTTP 1.1 way of using TCP when the established once TCP connection is used for sending several HTTP requests one by one. HTTP pipelining is the capability of client to send requests to server while responses to previous requests were not yet

Node.js pipelining HTTP client agent?

阅读更多关于 Node.js pipelining HTTP client agent?

问题 The HTTP client built into Node.js doesn't seem to support pipelining requests. However, it occurred to me that it may be possible to create an Agent that sets up pipelining in the background. There may be issues getting the response data back the way it should be, but perhaps the Agent could fake out some socket objects to make the HTTP client work like normal? Has this been done? Alternatively, is there an alternative HTTP client that is a drop-in replacement for the main that supports

Difference between HTTP pipeling and HTTP multiplexing with SPDY

阅读更多关于 Difference between HTTP pipeling and HTTP multiplexing with SPDY

Thanks to Google and Stack Overflow, I think I understood the difference between regular HTTP pipelining and HTTP multiplexing (e.g., with SPDY), so I made the diagram below to show the differences between pipelining and multiplexing based on three regular HTTP requests. My two questions are: Is the image correct? Is it true that if pipelining would not have the head-of-line blocking problem it would be as fast as HTTP multiplexing? Or did I miss an additional difference? igrigorik It's not incorrect, but there is an important aspect it omits. HTTP requires that you deliver the entire response

Implementation bugs For pipelining to work, responses must come back in the order they were requested. A naive server implementation might just send the response as soon as it has been calculated. If multiple requests are sent in parallel, and the first request one takes longer to process (e.g. processing a larger image), then the responses will be out of order. This is a problem for the client
