* Project Name:   HTTP Server in Java
* Programmer:   Abhishek K. Dhote
* Type:   Network
* Technology:  Java
* IDE:   Any
* Description:   This is the implementation of Hyper Text Transfer Protocol in Java.This program can be use as sever which is able to process requsts for HTML pages.

To execute the program using LOCALHOST follow the steps:-
1.install HttpServer.java on one system
2.configure your browser using following steps:
a.go to Tools
b.go to Internet Options...
c.go to Connections
d.go to Lan Setting
e.select Use a proxy server for your lan
f.make Address:
Code:
http://localhost & Port:100

3.run HttpServer.java
4.run browser
5.put filename.html into the bin of jdk
5.place a request using following format:-
Code:
http://localhost.filename.html/

where filename.html is the name of the file you
want to request.
