The header is the area at the top of a webpage, where you can find all sorts of interesting information.

The header is a part of your website that you can’t see, but it’s very important. The header contains all sorts of interesting information about your website, including:

  • Server name or IP address (the computer that serves up webpages)
  • Server version number
  • Language used on this server (e.g., English)
  • User agent (the browser you’re using to access this page)

What are HTTP headers?

HTTP headers are a collection of metadata that describe the content being sent from the server to the client. They’re used for everything from setting cookies to specifying cache control, but they can also be used to set various HTTP response headers (like Content-Type).

What do the different HTTP status codes mean?

When you visit a website, the server will return an HTTP status code. These codes are used to tell you if your request was successful and give information about what’s happening on the server.

There are many different types of HTTP status codes that can be returned by a website’s server, but most of them fall under these categories:

  • 200 – OK – The request was successful
  • 403 Forbidden – You don’t have permission to access this page or resource
  • 301 Moved Permanently – The requested resource has been permanently moved elsewhere
  • 302 Moved Temporarily – You’ll need to make another request with updated parameters before being able to view/access this new location
  • 404 Not Found – The requested resource could not be found
  • 500 Internal Server Error – Something went wrong on the server side
  • 503 Service Unavailable – The server is currently unavailable

What kind of redirection rules exist?

There are two types of redirects: 301 and 302. A 301 redirect is permanent and a 302 is temporary.

A 301 redirect tells search engines that the page has permanently moved to another location, so they should update their records with the new URL. This is preferable because it allows you to pass link juice from your old page onto its new home, which can help with SEO rankings if you have strong content on both sites (e.g., if you’ve updated an older post).
