According to my knowledge,

Application server is more capable of dynamic behaviour
than webserver. We can also configure application server to
work as a webserver.Simply application server is a superset
of webserver.

Webserver exclusively handles http requests.application
server serves bussiness logic to application programs
through any number of protocols.

Answer / priya

A Web server handles the HTTP protocol. When the Web server
receives an HTTP request, it responds with an HTTP response,
such as sending back an HTML page. To process a request, a
Web server may respond with a static HTML page or image,
send or redirect, or delegate the dynamic response
generation to some other program such as CGI scripts, JSPs
(JavaServer Pages), servlets, ASPs (Active Server Pages),
server-side JavaScripts, or some other server-side
technology. Whatever their purpose, such server-side
programs generate a response, most often in HTML, for
viewing in a Web browser.

The web server simply passes the request to the program to
handle it. The web server does not provides any
functionality beyond providing an environment in which the
server - side program can execute and pass back the
generated responses. The server-side program usually
provides such functions as transaction processing, database
connectivity and messing .

Application Server

While an application server exposes business logic to client
applications through various protocols like HTTP, TCP-IP
etc. All the web servers mainly deals with sending HTML for
displaying to a Web browser. An application server providers
allows the client to access the business logic for use. The
application server is used to run business logic or
dynamically generating presentation code. A J2EE application
server runs servlets and JSPs that are used to create HTML
pages dynamically. In this case, J2EE application server can
run EJBs ? which are used to execute business logic. An
application server is more capable of dynamic behaviour than
webserver.
