Lecture notes
Application server:
- An application server is a software engine that delivers applications to client computers or devices
- It should handle most, if not all, of the business logic and data access of the application
- benefits of application server:
1] ease of application development
2]and centralization - identified with the Sun Microsystems J2EE platform; however,
- it has also come to encompass servers of web-based applications, such as integrated platforms for e-commerce, content management systems, affiliate management systems and occasionally, even applied to simplistic web-site page builders. The paradigm is more similar to mainframe based applications than traditional client-server.
Apache web server

Hungry ? Wanna have a cookie ?
Cookies provide a means for a Web server to induce a client to store information about itself which can subsequently be called up by the Web server when required. This might be information which the user has supplied about themselves, their preferences or their requirements via forms input. The oft-cited example is the shopping list which might be added to from time to time. Cookies are currently implemented by Netscape and Internet Explorer.

Web servers
Working:
Process of getting a Web page onto your computer screen:
The browser broke the URL into three parts:
The protocol ("http")
The server name ("www.howstuffworks.com")
The file name ("web-server.htm")
The browser communicated with a name server to translate the server name "www.howstuffworks.com" into an IP Address, which it uses to connect to the server machine.
The browser then formed a connection to the server at that IP address on port 80.
Following the HTTP protocol, the browser sent a GET request to the server, asking for the file http://www.howstuffworks.com/web-server.htm.
The server then sent the HTML text for the Web page to the browser.
The browser read the HTML tags and formatted the page onto your screen.
