WWW

WWW which is expanded as World Wide Web is generally a part of any website's URL. You can see any website's URL starting with www. It is just a sub-domain but which all DNS record should contain for sure. Let's take three of my blogs for explanation.

Redirect Subdomains

While explaining about URL, I told that http://forum.krishnainfotron.com/ and http://search.krishnainfotron.com/ as Redirect Sub-domains.

What is a redirect?
When a URL redirects to another URL, its called a redirect.
