About HTTP Status Checker
This HTTP Status Checker page is organised around the task described in the tool interface. Check HTTP status codes and server responses. The result changes when the source data or selected options change, so it is easy to run a second comparison.
A practical way to use it is to run a fresh diagnostic after a hosting, DNS, certificate, redirect, content or performance change. Start with a representative input, inspect the first result, then adjust one setting at a time if you need a different outcome.
The checker uses the public target you enter to make a diagnostic request. Do not place credentials or private access tokens in a URL.
