What Does an HTTP Header Tell You?
The Hypertext Transfer Protocol (HTTP) is the language of the Internet. It is the communication protocol that tells us how web pages communicate, how to request a web page, and how to handle responses of a web site.
When you type a website URL into your browser, your browser sends an HTTP request to the web server of the site you entered. The type of response that the Web server returns determines how your browser handles the response. A typical response is HTTP/1.1 200 OK, meaning that the Web server is responding and the requested URL exists on the server. The browser can then proceed to render the contents of the page. However, a 404 Not Found error indicates that an URL is invalid or was possibly mistyped.
What Kind of HTTP Headers Are There?
There are many HTTP headers that are potentially included in a HTTP header response.
There are actually dozens of headers that can be found in a typical request or response, which define things like the expiration date of a page, the status of an URL, character sets, and much more.
