Error 404 - Page not found

A Carl and Jerry Adventure
With apologies to John T. Frye

A LATE HOUR of an evening in January found Carl and Jerry busy in the electronics laboratory of Parvoo University. Carl was seated in front of the computer looking intently at the glowing screen.

"Carl, I don't understand what this '404 error' is all about, do you?"

"Well, Jerry, it probably means that your computer has done exactly what you told it, or at least what you think you told it. Computers are like that."

"But I am sure that I told it the right thing. Besides, what could possibly go wrong? I just click on a link and I get where I want to go, right?"

"Yes," Jerry answered, "but a number of things can happen. Let me explain some of them to you:

	The page you requested may have moved. Links from other sites and search engines may point to an old address. Click on "Back". Then look at the page information in the address bar and try to find a similarly named page on one of the menus.
	The department may have been renamed. Some sections of the site have been renamed. We do use re-direction pages but after some months they are removed.
	There may be a bad link. Our menu system is being streamlined. Some large sections have been split into several smaller ones, each with its own menu. Many of the frequently changing items now have their own section. Bad links can happen. If you find a broken link please tell us.
	The page may not be here any more. Try using the Search box to locate a similar page. Or, browse through the menus to find the article. We try not to remove old articles but it does happen on occasion.

"As you can see," Jerry concluded, "there can be a number of reasons for a 404 error."

Carl replied, "Yes, but you forgot two more likely reasons."

"Oh? What are they"?

Carl answered, "Well, you could have developed a case of "fumble fingers" and your computer did exactly what you told it!

"Fumble Fingers?"

"Or", he continued, "Eight-to-Go could have decided to make a snack out of the computer mouse. Cats are like that."
