Developing & Hosting a Web Page
(Web Development Lecture 2)
1
Today is our 2nd Web Dev lecture
During our 1st lecture about the Web …
• We answered various questions about the Web.
• How it works, How it is structured, etc.
• We also commented about the future shape of the
Web: the Semantic Web, and how it is different from
the Web of today.
• Today’s Web is targeted squarely at us, humans.
Whereas, the Semantic Web is being constructed in
such a way that it is easily understandable for the
computers

Learning Goals for Today
1. To develop your personal Web page
2. To upload your Web page to VU’s Web
server so that it becomes visible on the
Internet as http://www.vu.edu.pk/~xxxxxxxx/
where xxxxxxxx is your user ID

But first …

and made it available over the Internet through the URL

</HTML>
This HTML document was developed
in a plain-text editor called notepad
18
19
After typing the code into notepad, I
saved it as index.html
To check if I have done everything right,
I double clicked on icon of the saved file
index.html
Double clicking on the icon launched the
Web browser displaying my index.html
20
My Web page is done!
21
Problem!
My Web page is visible only on my
computer. It would be nice if it was
also visible on the computers of all
my friends and relatives as well.
22
Solution!
I need to upload my Web page to a Web
server that is connected to the Internet
As a result, my Web page will become
accessible to anyone with a computer
hooked up to the Internet
23
Upload Process
I went to the Web server upload
page on the VU Intranet and
uploaded my Web page to my
account on the VU Web server
24
25
Eureka!
26
My Web page is now
accessible from all of the
millions of computers
connected to the Internet

28
Enough about mine …
Here is how you can develop your personal Web page
and make it available on the Internet as
http://www.vu.edu.pk/~xxxxxxxx
29
Developing Your Own Web Page
Open notepad, type in the HTML code, and save
it as index.html on your PC’s desktop
30
Developing Your Own Web Page
Log on to the VU Intranet and upload that
index.html from your PC’s Desktop to your
account on VU’s Web server
31
That is it!
Your Web page is now accessible on the Internet through the URL:
http://www.vu.edu.pk/~xxxxxxxx
where xxxxxxxx is your user ID
