have a significant impact on performance. I served as the "protocol cop" within the Apache Group, writing code for the core http parsing functions, supporting the efforts of others by explaining the standards, and acting as an advocate for the Apache developers' views of "the right way to implement http" within. Rest accomplishes this by defining a resource to be the semantics of what the author intends to identify, rather than the value corresponding to those semantics at the time the reference is created. This chapter described the experiences and lessons learned from applying rest while authoring the Internet standards for the Hypertext Transfer Protocol (http) and Uniform Resource Identifiers (URI). Unfortunately, there is no way for a client to indicate to a server that it may have resource limits, which leads to problems when resource-constrained devices, such as PDAs, attempt to use http without a device-specific intermediary adjusting the communication. Several experimental extensions had been added to http to allow for proxies, but for the most part the protocol assumed a direct connection between the user agent and either an http origin server or a gateway to legacy systems. 6.2.1 Redefinition of Resource, the early Web architecture defined URI as document identifiers. That is why http goes through firewalls.
Aside from its name, the URI syntax has remained relatively unchanged since 1992. The http server is replaced. Mismatches occur when, due to ignorance or oversight, a software implementation is deployed that violates the architectural constraints.

In other words, it provides a tentative form of protocol negotiation on the http scale. Html 18 is an example of a media type that, for the most part, has good latency characteristics. If the server supports the improved protocol and desires to switch, it simply responds with a 101 status and continues on as if the request were received in that upgraded protocol. It also allows metadata to be sent at the end of the message as trailers, enabling the creation of optional metadata at the origin while the message is being generated, without adding to response latency. With this, you can give your clients multiple fee packages. Rest is not intended to capture all possible uses of the Web protocol standards. What makes http significantly different from RPC is that the requests are directed to resources using a generic interface with standard semantics that can be interpreted by intermediaries almost as well as by the machines that originate services. Unfortunately, mime and http have very different goals, and the syntax is only designed for mime's goals. Rest's definition of resource derives from the central requirement of the Web: independent authoring of interconnected hypertext across multiple trust domains. This will also add up to your revenue regardless of the package they avail.
