URL Definitions

Dissecting a URL

http://www.mccc.edu/student_library.shtmlhttp: You use Hyper Text Transfer Protocol to access

this page// tells us that the page is hosted remotely

www tells us that the page is on a world wide web server

mccc tells us that the page is part of the Mercer County Community College’s network

edu tells us that this site is an educational institution

student_library.shtml is the specific file for this page

Using a URL to your advantage

• Sometimes a page you ask for no longer exists

Error 404 page not found• The page may be gone or the URL may

have changed• Try slicing off the last piece* of the URL

and see what you get. It may lead you to the page you wanted

• This method also works for pages you like and want to look for more on the same topic* You may need to do this a couple of times

Moving back & forward

• You already know to use the back & forward button to move around one page at a time

• By right clicking on your back button, you get a list of the places you’ve visited recently
