HTTP Header Checker

When you have a website, you’re responsible for making sure it is working properly. If your site is laggy or simply not loading, you could miss out on a ton of potential customers. If the URL and site aren’t working properly, you’ll need to test it to find out why.

But how do you get this information? One of the best ways to view and check the status of a website or server is to check the HTTP headers.

What Are HTTP Headers?

HTTP headers are part of a website response that are normally hidden and can only be seen by a browser. They are a bit of code that informs the browser what it should do when viewing and/or opening the website. Essentially, they transfer data from a browser to the server and vice versa. These headers carry important information about the browser, the webpage, and the server itself.

In general, there are two different types of HTTP headers: the HTTP request header and the HTTP response header. The request header is sent to a server, which then sends back a response header.

HTTP Status Codes

While HTTP headers can help you see important information like software versions, content types, and cookie strings, the status codes are arguably the most important. An HTTP status code will quickly and easily tell you the status of a given website. A good and functional URL should always return with a response of 200 to show a successful request has been made.

In addition to 200, a few other common status codes include:

200 – The request has succeeded

301 – The requested resource has been assigned a new permanent URI and any future references to this resource SHOULD use one of the returned URIs.

302 – The requested resource resides temporarily under a different URI.

401 – The request requires user authentication.

404 – Not Found, he server has not found anything matching the Request-URI.

500 – Internal Server Error

503 – Service Unavailable,he server is currently unable to handle the request due to a temporary overloading or maintenance of the server.
