The amount of information you can send back using a GET is restricted as URLs can only be 1024 characters. A POST request is a request to post (to send) form data to a resource on the server.

Yes. Preemptive termination of request processing on an error condition is a good way to maximize the throughput of a high-volume JSP engine. The trick (asuming Java is your scripting language) is to use the return statement when you want to terminate further processing. For example, consider:<% if (request.getParameter("foo") != null) {// generate some html or update bean property} else {/* output...

Answer Question  Select Best Answer

A servlet can handle multiple requests concurrently, and can synchronize requests. This allows servlets to support systems such as on-line conferencing. Servlets can forward requests to other servers and servlets. Thus servlets can be used to balance load among several servers that mirror the same content, and to partition a single logical service over several servers, according to task.

Implementing an interface means providing a specific behavior to your class. Since jsp are to be interpreted by servlet-container and will then be executed as a servlet, it cant be used for that extended behavior. Thus no use of implementing it.Sandeep Jindal
