How redirection works in HTML


I see following entry in index.html of ROOT directory in my apache-tomcat (location: /opt/apache-tomcat/current/webapps/ROOT/index.html)

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

The meta refresh tells a browser to automatically refresh the current web page after a time interval. Usually the content value is the number of seconds, generally in this format:

However, you can also append a URL in the content, and the browser will redirect to that URL.

The format would be:

content="<seconds>;<optional URL>"
Since your content = zero seconds (0), the browser will immediately redirect to that web page.
