HTTP is the protocol used to transfer data between the web server and browsers. When a browser requests a HTML document from a web server, the browser send an URL (web address) with a request header. The server respond to a browser by providing a HTTP response header and the requested document (if exists). This tool extracts the HTTP server response headers, and displays them to you.
Enter a website URL:
You may enter an URL with or without the protocol. If no protocol designator was specified, the address will be preceeded with http://.
An HTTP header check is a diagnostic tool that allows you to view the headers of an HTTP request and response between a web server and a client (typically a web browser). HTTP headers are additional pieces of information that are sent along with the content of a web page, and they provide details about the request and response, including the date and time of the request, the type of web server being used, and any cookies that may be associated with the request.
HTTP header checks can be useful for troubleshooting issues with web servers or web applications, as they can provide insight into the behavior of a web server and the data that it is sending and receiving. For example, if you are experiencing slow load times on a particular website, an HTTP header check can help you identify any issues with the server or network that may be causing the delay.
Some common types of information that can be found in HTTP headers include:
In summary, an HTTP header check can be a useful tool for understanding the behavior of web servers and applications, and for troubleshooting issues with website performance and functionality.
