Differences between webserver and Application Server

Difference between web server and application server:

Webserver 1) Webserver handles the HTTP protocol request.   When  the Web server receives an HTTP request,  It responds with an HTTP response, such as   sending back an HTML page. 2) Web Server serves static HTML pages or    gifs, jpegs, etc., and can also run code written   in CGI, JSP etc. 3) Web Server only supports Servlets and JSPs.

Application Server 1) Application Server serves business logic     to application programs through any number    of protocols 2) Application server is more capable of    dynamic behavior than webserver. We can   also configure application server to work   as a webserver. Simply application server is a    superset of webserver. 3)Application Server supports distributed     transaction and EJB. 4) An Application Server is used to run business  logic or dynamically generated presentation code.  It can either be .NET based or J2EE based
