Chromium Blog: A 2x Faster Web

  • It is designed specifically for minimizing latency through features such as multiplexed streams, request prioritization and HTTP header compression.

HTTP/1.1: Method Definitions

  • it is possible that a sequence of several requests is non-
    idempotent, even if all of the methods executed in that sequence are
    idempotent.
  • This method allows the client to
    determine the options and/or requirements associated with a resource,
    or the capabilities of a server, without implying a resource action
    or initiating a resource retrieval.

NginxHttpCoreModule

    • To use regular expressions, you must use the a prefix:


      1. ~* for case insensitive matching
      2. ~ for case sensitive matching
  • the prefix "=", which matches an exact query only.

TerrorZone: File (MIME) Types (Web Design in a Nutshell, 2nd Edition)

  • The browser determines how to handle the file based on that
    information -- whether to display the contents in the window, or
    to launch the appropriate plug-in or helper application.
  • MIME
    (Multipurpose Internet Mail Extension), which was originally
    developed for sending attachments in email.

Communicating with a Server - Google Web Toolkit - Google Code

  • GWT allows only asynchronous
    server calls. When sending an HTTP request, the client code must register a callback method that will handle the response (or the error, if the call fails).
  • <inherits name="com.google.gwt.http.HTTP" />

HTTP/1.1 Keep-Alive header

  • The Keep-Alive field is NOT a standard HTTP header field and may not be supported by all clients.

Apache Tomcat Configuration Reference - The HTTP Connector

  • If the PATH(Windows) or LD_LIBRARY_PATH(on most unix system)
    environment variables contain the Tomcat native library, the APR connector
    will automatically be configured.
  • The default value is to use the value that has been set for the
    connectionTimeout attribute.

Apache Tomcat 6.0 - Connectors How To

  • When using a single server, the performance when using a native webserver in
    front of the Tomcat instance is most of the time significantly worse than a
    standalone Tomcat with its default HTTP connector, even if a large part of the web
    application is made of static files.

page 6 > Asynchronous HTTP and Comet architectures - JavaWorld

  • The long poll is one of the two Comet strategies to reduce the frequency of HTTP calls
  • The second Comet strategy is response body streaming.

  • streaming doesn't mean that the data will be read or written directly to the network. All read and write operations work on internal
    socket buffers. When a write method is called, the operating system kernel transfers the data to the socket's send buffer. Returning from the write operation just says that the data has been copied to this low-level send buffer. It doesn't say that the peer has received the data.
  • Unfortunately, the
    current Servlet API 2.5 supports neither non-blocking data streaming nor asynchronous message handling.

  • broken into several TCP segments when sent.
  • Data transfer fragmentation can be hidden at the API level by accessing the body data as a steady and continuous stream. This
    approach, known as streaming, avoids the need to buffer large chunks of data before processing it. Streaming can also reduce
    the latency of HTTP calls, especially if both peers support streaming.

page 1 > Asynchronous HTTP and Comet architectures - JavaWorld

  • In this article I introduce asynchronous, non-blocking HTTP programming and explain how
    it works.
  • Asynchronous message handling also enables HTTP pipelining, which you can use to send multiple HTTP requests without waiting for the server response to former requests. The response
    messages will be returned by the server in the same order as they were sent. Pipelining requires that the underlying HTTP
    connection is in persistent mode, which is the standard mode with HTTP/1.1.

Comet Daily » Blog Archive » Comet and HTTP Pipelining

  • duplex communication in HTTP based on request content streaming in XHR requests. A request could use “chunked” transfer encoding, and progressively send parts of the request body. While the client streaming of the request body is taking place, the response could then be returned to the user agent and also stream data for the response body.
  • being able to handle the response after sending part of the request, but prior to finish sending the entirety of the request.
