Check and inspect HTTP headers from any website URL. This tool helps you understand how your web server responds and what data is passed with requests.

Understanding HTTP Headers

HTTP headers are key-value pairs sent between the client and server during a request or response. They play a crucial role in communication, authentication, caching, content-type declarations, and more.

Why Use an HTTP Header Viewer?

Inspecting HTTP headers is important for debugging server configurations, understanding how APIs behave, ensuring SEO-friendly setups, analyzing cookies, and implementing security headers like X-Frame-Options and Content-Security-Policy.

Common HTTP Headers

Content-Type: Specifies the media type of the resource
Cache-Control: Controls how caching is handled
Server: Identifies the server software
Set-Cookie: Used to set cookies in the user's browser
X-Frame-Options: Provides clickjacking protection

SEO Implications of HTTP Headers

Headers can affect your site's SEO performance. For example, correct cache headers help improve speed, while proper redirection via 301/302 status codes ensures search engines index the correct URL.
