Lecture 6Developing & Hosting a Web page (Web Development Lecture 2)

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/~xxxxxxx/

where xxxxxxx is your user ID

But first …How I developed my personal Web pageand made it available over the Internet through the URL

This HTML document was developed in a plain-text editor called notepad

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

My Web page is done!

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.

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

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

Eureka!

My Web page is now accessible from all of the millions of computers connected to the Internet

http://www.vu.edu.pk/~altaf/index.html

http://www.vu.edu.pk/~altaf

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/~xxxxxxx

Developing Your Own Web Page

Step 1Open notepad, type in the HTML code, and save it as index.html on your PC’s desktop

Developing Your Own Web Page

Step 2Log on to the VU Intranet and upload that index.html from your PC’s Desktop to your account on VU’s Web server

That is it!Your Web page is now accessible on the Internet through the URL:

http://www.vu.edu.pk/~xxxxxxxwhere xxxxxxx is your user ID
