What is an HTTP Header?

HTTP headers are used to provide information about the HTTP request or response. Usually, HTTP headers are not seen by users because they are only handled internally by web servers.

HTTP headers can be used to determine how a browser should render the page on the screen, what language it should use, what content encodings it should support, and many other things that will influence how a web page is rendered on the screen.

 

What are the Most Important Header Fields To Check For Server Diagnostics?

The most important header fields are the http response status code and custom status codes for https site. It is also important to know what does it mean when the response is 200?

The server's response tells us if it is successful or not, so knowing the status code of the server's response is very useful. There are three main types of http response codes:

  • 2XX - Successfully completed communication with the web server
  • 3XX - Request was redirected to another location
  • 4XX - Client error that prevented communication with the web server
  • 5XX - Server error on behalf of the web server

 

Why is it Important to Know HTTP Headers?

HTTP stands for Hypertext Transfer Protocol. It is the set of rules that govern how information is exchanged between a web server and a web browser.

HTTP headers are data that is sent to the client before the requested content, or after it has been delivered. The header contains information about the body of the message, including its length, date, type of encoding or any other special instructions.
