Simple CURL HTTP Header Request, URL Test Tool

This page provides a raw PHP CURL HTTP Header URL analysis tool. The tool requests the HTTP header information given any URLs. You can check if any web page is compressed by looking for gzip or deflate in the http header. And the URL redirections are parsed and unrolled. You can also use the API easily to get realtime CURL output.
The results will be cached and kept for an hour.
