i m new in testing field so i want to know what is the difference between web server and application server n how the testing r done in both the server
Click the blue Advanced button and search this forum and the web testing forum for "web client server" and "client/server" and other such related terms.
A Web server is a program that, using the client/server model and the World Wide Web's Hypertext Transfer Protocol (HTTP), serves the files that form Web pages to Web users (whose computers contain HTTP clients that forward their requests)
WebServer is supposed to support HTTP and/or FTP, SSL HTTPS, etc protocols..
An Appserver is an extension of WebServer, which basically should support all the technologies in J2EE spec (JavaServlets, JSP, JMS, blah blah blah ...)
