Web Server Definition
A web server is a service that handles specifically requests in the HTTP protocol format. The server responses to requests made using the HTTP format, and in turn responds using a valid HTTP response. All responses from a web server follow the W3 standards for HTTP protocols.Web server can be either a computer program or a computer running a program that is responsible for accepting HTTP requests from clients, serving back HTTP responses along with optional data contents, which usually are web pages such as HTML documents and linked objects on it.This is mainly used for Servlets and JSP.
Or we can say Web server can be either a computer program or a computer running a program that is responsible for accepting HTTP requests from clients, serving back HTTP responses along with optional data contents, which usually are web pages such as HTML documents and linked objects on it.
The Web Server does not support the concept of multi-threading
As web servers are well suited for static content and app servers for dynamic content, most of the production environments have web server acting as reverse proxy to app server. That means while service a page request, static contents such as images/Static html is served by web server that interprets the request. Using some kind of filtering technique (mostly extension of requested resource) web server identifies dynamic content request and transparently forwards to app server
Some more defination:-
A Web server is process running on a machine that "listens" specifically on TCP/IP Channel using one of the "internet" protocols, (http, https, ftp, etc..) and does whatever it does based on those incoming requests... Generally, (as origianly defined), it fetched/generated and returned an html web page to the client, either fetched from a static html file on the server, or constructed dynamically based on parameters in the incoming client request.
Some Web Server are
Tomcat : Servlet
Jetty : Servlet
Apache : Php, CGI
Application Server
An application server is a service that handles specifically requests for business operations, and performs business logic. It is not limited to the HTTP protocol, but can operate using that protocol if it fits the business requirements.
It can be provided other protocol support such as RMI/RPC
In Application Server we have features like connection pooling,
isolation pooling, multi-threading, and majorly the Transaction feature which is not there in Web Server.Applicatin server supports distributed transaction and EJB's
Web servers support to deploy .war files only while Application servers support to deploy .war and .ear files.It can also provid other protocol support such as RMI/RPC
Some Application Servers are
WAS : EJB
JBoss : EJB
WebLogic Application Server : EJB
Some more task taht are done by Application server but not web server are
1)A (proprietary or not) API
2)Load balancing, fail over...
3)Object life cycle management
4)State management (session)
5)Resource management (e.g. connection pools to database)
