Check the header information of a server request.


Use the server headers check tool to receive a report on the information embedded into the header.

What information does a server headers check tool provide?

After entering a URL into the server headers checker, you will see the utility results displayed. This could include the following information:

  • Content type
  • Date
  • Server
  • Set-Cookie
  • Connection
  • Content-Encoding
  • Vary
  • Cache-Control
  • Transfer-Encoding
  • Expires
  • Content-Length
  • X-Powered-By
  • Link
  • Pragma

Each of the returned results is fairly self-explanatory. While each visitor may have a different reason for determining the server headers of a particular URL, the information provided should help you in some way. It doesn't provide every possible piece of information - for example, the URL's IP address, which can be found using the DNS lookup tool. However, the server headers check tool still provides a great deal of valuable information to users.

The tool has multiple uses. Whether you want to know what kind of server hosts the site or if the page serves up via a cached file, the server headers check helps. For users who have or manage their own website, the tool helps determine if their status code returns the correct response.

About the server headers check tool

Similar to email headers, HTTP headers are hidden parts of websites that can only be read by the browser. The headers tell the browser how the website should behave when the browser opens the page. The headers give the webmaster a lot of control over how the webpage behaves within the browser.

Essentially, the server header refers to the software being used to handle the request from the server that generated the response. Although many of the more popular HTTP header responses are listed above, there is a complete list of HTTP headers at the W3 Consortium’s Status Code Definitions page. Access their page if you find that the HTTP header you're looking for is not as common or harder to find.

The server header check is a simple and thorough way for webmasters to check that their headers behave as intended.
