Check HTTP status codes, response times, and monitor website availability. Detect 404 errors, 500 errors, redirects, and server issues.
Checking HTTP status...
HTTP status codes are three-digit numbers returned by web servers to indicate the outcome of a request. They provide information about whether a request was successful, encountered an error, or needs further action.
Why check HTTP status codes? Monitoring status codes helps identify website issues, track redirects, optimize SEO, and ensure proper website functionality.
Provisional response indicating the request was received and continuing processing.
The request was successfully received, understood, and accepted.
Further action needs to be taken to complete the request.
The request contains bad syntax or cannot be fulfilled.
The server failed to fulfill a valid request.
