Basic Definitions

Web client- machine that initiates internet request Web server – machine that services internet request Browser - software at the client side to interact with web data Intranet – an internal network of computers confined to a single place Extranet – when two or more intranets are connected with each other, they form an Extranet – e.g, Virtual Private Network Internet – a global network of networks is defined as internet Internet presents a two-way client server communication model

as shown in Fig. 1 below: Client-Server Model Fig. 1 What is the WEB?

The Web is a protocol that uses the internet as the communication structure. It links documents stored in computers that communicate on the internet. It is based on Hypertext Transfer Protocol (HTTP) - native protocol of WWW designed for making web page requests.

HTTP is a four step process per transaction

1. Client Makes an HTTP request for a web page Makes a TCP/IP connection 2. Sever accepts request Sends page as HTTP 1 Client downloads the page 2 Server breaks the connection HTTP is stateless because in the fourth step the server breaks the connection. We can say, therefore: Each operation or transaction makes a new connection Each operation is unaware of any other connection Each click is a new connection

Side Effect of HTTP Transfers

A record is left of all web transaction in a file that resides at the server called common log file. Good news is that some user data (record of his visits to the web sites) is recorded in a particular format in the log files. Bad news is that user privacy is not maintained.

What can you do with this data?

Rearrange your site by knowing which portions of your web site are popularly accessed and which are ignored by the users Change your marketing strategy – e.g., you can introduce some promotional scheme for boosting the sale of ignored items Make a mailing list – you can trace the location from where customers are visiting and prepare a mailing list for marketing purposes
