Enter a URL
Whenever a webpage is requested from the browser, the web server will return a HTTP response. The response contains a header data having useful information. Generally you need the server response code to understand the result of the request. For example, status code 200 indicates everything is fine and the server returned the requested page successfully.
When your site is not accessible, you can use our free HTTP header checker tool to find the server response code and take necessary action. For example, status code 404 indicates that the page is not available. Probably, you might have wrongly deleted the page or modified the URL without setting up proper 301 redirect.
