Network Tools
HTTP Headers Checker
Enter a website address to see the HTTP response headers it sends back.
How it works
The RouteLearn server makes a normal HTTP request to the address you enter. This is the same kind of request a browser makes when loading a page. The tool shows you every header that comes back in the response, plus the status code and any redirects it followed along the way.
FAQ
- What are HTTP headers, in simple terms?
- Headers are extra information a web server sends along with a page. They're separate from the page content itself. Headers say things like what kind of content this is, whether it's cached, what security rules the browser should follow, and what server software answered the request.
- Why would I check a site's headers?
- You might check headers to debug caching issues, confirm a security header (like Content-Security-Policy) is actually being sent, see what server or CDN a site runs on, or find out where a redirect actually sends visitors.
- Does this follow redirects?
- Yes, up to 5 hops. It shows you the full chain, so if a URL bounces through several redirects before landing on its final destination, you can see every step, not just the last one.
