What is HTTP Headers & Redirect Checker?
Web servers communicate critical information through HTTP response headers (like Caching policies, Content Security Policy (CSP), and Server types). This tool performs a real, server-side fetch from our backend infrastructure. Because it runs server-side (unlike pure browser fetch requests), it bypasses CORS restrictions, captures exact redirect chains (like 301 Moved Permanently), and returns the raw headers exactly as search engine bots and API clients receive them.
How to Use HTTP Headers & Redirect Checker
- Enter any valid HTTP or HTTPS URL into the input field.
- Click the "Analyze" button to initiate a server-side request.
- View the status code, response time, and redirect trail.
- Inspect the full list of raw HTTP headers returned by the server.
Frequently Asked Questions
Why does this tool need a server-side API?
Browsers strictly enforce Cross-Origin Resource Sharing (CORS) rules. If we used client-side JavaScript, most websites would block the request, hiding valuable header data or failing entirely.
What is a HTTP 301 redirect?
A 301 is a permanent redirect indicating that the requested resource has been definitively moved to a new URL. Our tool correctly halts at the first redirect so you can inspect the "Location" header.
