A complex example is described in RFC 3261: the proxy server is used as the communication path. The SIP Proxy Server initiates a request on behalf of other clients. In many cases, as the routing mode, the SIP request is forwarded to another device that is closer to the final destination (that is, the called end. Therefore, the SIP Proxy Server plays two roles: the server role when receiving the request a

BZByte EZAjax is an open-source Ajax Web framework. The BZByte Ajax framework uses server-side Java to create DOM instead of web browser JavaScript. All updates to the framework are GUI-driven, so you don't have to worry about exposing application code and remote interfaces. GUI updates quickly and does not rely on the speed of end user computers.

Otherwise, "Oh, it's no different from our previous products. It doesn't mean we have to spend so much money if we have to maximize or close a few buttons ." That's terrible.

SIP is a communication mode based on a request response similar to HTTP protocol. Each communication includes a request for a function and requires at least one response. In this response, Alice's soft phone sends an invite communication request containing BBO's sip URI boycott. Invite is an example of a SIP request, indicating that the requester (Alice) wants the service provider (Bob) to respond. An invte request contains a series of header fields ). The hea

DWR (Direct Web remoting) is a web Remote Call framework. using this framework can make Ajax development very simple. using DWR, you can use JavaScript on the client side to directly call the Java method on the server side and return the value to Javascript, just like calling it directly on the local client (DWR dynamically generates javascrip code based on Java

Dom parsing is a one-time read of an XML file and constructed as a DOM object for the program to use, the advantage is easy to operate, but less memory. Sax is parsed in an event-driven manner and consumes less memory, but programming is complex14, what frame are you using (Rack package)?

Introduction
Ajax (Asynchronous JavaScript and XML) terminology is used to represent a set of technologies that support the creation of rich Internet applications (Rich Internet application). By using these technologies, you can create Web applications that are responsive and have a rich user interface similar to desktop applications. These technologies allow you to retrieve data asynchronously in the background without affecting the displayed page, and you
