View your website's HTTP Headers to diagnose problems or Verify HTTP Redirects.
What are HTTP headers?When you visit a website page in your browser there are a few things that happen:
More information is returned that you do not see in a web browser during the 3rd step. Information about the server itself, when the page was modified, it's encoding etc. These are the HTTP headers.
Is there a way to View HTTP headers in my browser?If you are using Firefox you must download a plugin called Firebug. Chrome has a firebug-ish interface built-in that allows you to view all kinds of information. IE, you are out of luck(what a piece of junk). This easiest way of course is to just use our http viewer like you are now.
How do I Properly Move or Rename a Website Page?Search engines like Google have a complicated process when indexing a new website page. Essentially the longer a page exists, the more reliable and trustworthy it is deemed.
If you change a filename or move domains you are basically hitting the reset button on all that trust you have built up. Even worse, any clicks from a search engine will direct users to a 404 Not Found page.
You must use a 301 redirect within your http headers for that page to show Google this old page still exists but at a different location.
What is a 301 Redirect?The 301 redirect is a status returned by a webserver inside the http headers to notify a web browser or a web crawler that this page has been moved permanently to a new location.
You can either do this in your webserver configuration file or by using code like this in an .htaccess file:
