what is the difference between application server and web
server?

Answer Posted / hari krishna gajula

A Web server exclusively handles HTTP requests, whereas an
application server serves business logic to application
programs through any number of protocols

In detail:

A Web server mainly deals with sending HTML for display in a
Web browser, an application server provides access to
business logic for use by client application programs. The
application program can use this logic just as it would call
a method on an object (or a function in the procedural world).

For Eg: If we take Weblogic or Websphere which serves as
application servers i.e. web container as well as ejb container
where as tomcat or resin servers are only web servers

Conclusion here is application servers can be used as a web
servers but the converse is not true.
