What is an HTTP Header Checker?

An HTTP Header Checker is a tool that allows you to view the metadata sent by a web server when a URL is requested. These headers contain vital information about the server, the content type, caching instructions, security policies, and more.

Why check HTTP headers?

Debugging website redirect issues
Verifying security header implementation
Checking server-side caching (Cache-Control, ETag)
Analyzing server response times and status codes
Identifying server software and technology stacks

Why correct headers matter?

"Correct HTTP headers ensure your site is secure, fast, and search-engine friendly. They are the backbone of modern web communication."
