Install a Web Server

What is a Web Server and Why we need it ?
A computer program that is responsible for accepting HTTP (Hyper Text Transfer Protocol) requests from clients (user agents such as web browsers), and serving them HTTP responses along with optional data contents, which usually are web pages such as HTML documents and linked objects (images, etc.). (From Wiki)

We can use it for offline testing/developing purposes

So what all things you need to get started ?

1) Windows 2000/XP/ Win7)
2) A drive/partition on your PC to group everything neatly/
Default installation dir C:\Program Files will work just fine
but it will get clumsy by time
3) A Web Server
Aprelium Abyss Web Server X1 or
Apache Web Server (Will talk about apache later)
cause for beginners I prefer Abyss Web Server (both are free ones)

Step 1
Download the Abyss Web Server from this link
http://www.aprelium.com/abyssws/download.php

Step 2
Install it :)
For help plz refer to http://www.aprelium.com/data/doc/2/abyssws-win-doc-html/install.html
[It's perfect and I can save some writings ;) ]
though it would be better if you change the installation path to some other drive like I said earlier
like D:\Abyss

Step 3

Test the server, after the installation, run the program, type
127.0.0.1 or just 'localhost' in your web browser, if the success page shows, then everything's fine
Note: All the files for the website should be placed inside the "Drive:\Abyss Web Server\htdocs"

Step 4
Local Domain name
For testing purpose it's better to have a correct domain name than the
127.0.0.1 or the 'localhost'
Follow these steps to provide a local domain name

Go to C:\windows\system32\drivers\etc

Open the file 'hosts' in notepad (make a copy before that)
add "127.0.0.1 www.myweb.com" below the line "127.0.0.1 localhost"
like this
------------------------------------------------------------------

blah blah..........

# 38.25.63.10 x.acme.com # x client host

127.0.0.1 localhost
127.0.0.1 www.myweb.com
127.0.0.1 www.yourname.com

-------------------------------------------------------------------

After editing save the file, now you can type www.myweb.com or www.yourname.com in the address bar to show your local website/page, when the server is running :)

Note: Don't give the name of any existing website, else the real site won't load even if the Web Server is not running, this method can also be use as
a parental guardian, by assigning the "not to visit" sites as 127.0.0.1

Example: on the hosts file placing "127.0.0.1 www.youtube.com" will restrict access to the real site
and will show a page not found error
