So, you run into those
every day, with a bad connection even all day long. Most of the time you
would not even pay attention to them but they are there: 404 error pages.
What are 404 error pages:
When you browse the web and a particular page
can not be found by your browser, you are served an error page by the
server of the web site you are visiting, called 404 (which means that the
page does not exist).
Since the page might only be inaccessible
temporarily it is suggested to hit the
Refresh button
on your browser toolbar, or try to visit that page again later.
Sometimes though you are dealing with a page that really
does not exist anymore physically. In this case you would always be served
the same error message no matter how often you hit that Refresh button.
These
customized 404 error pages serve the purpose of offering the web site user
an apology or alternative way of finding back into the content the web site
deals with, or both.
