Frequently Asked Questions
HTTP response headers are components of HTTP responses sent by web servers to clients (like browsers). They contain metadata about the response, such as content type, caching directives, security policies, and server information. These headers control how browsers and other clients process the received content.
HTTP headers play a crucial role in website security. Security headers like Content-Security-Policy, X-Content-Type-Options, and Strict-Transport-Security help protect against common web vulnerabilities such as cross-site scripting (XSS), clickjacking, and man-in-the-middle attacks. Regularly checking these headers ensures your security configurations are properly implemented.
HTTP headers impact SEO in several ways. Canonical headers prevent duplicate content issues, cache-control headers affect page load times (a ranking factor), and X-Robots-Tag headers control how search engines index content. Additionally, proper implementation of security headers can positively influence search rankings as Google considers website security in its algorithm.
CORS (Cross-Origin Resource Sharing) is a security mechanism that allows or restricts web resources from different origins. CORS headers like Access-Control-Allow-Origin specify which domains can access resources on your server. Proper CORS configuration is essential for web applications that consume APIs from different domains.
Yes, our HTTP headers checker can analyze headers from any publicly accessible website. However, some websites may have security measures that prevent external tools from accessing their headers. Additionally, checking headers of websites behind authentication or on private networks requires access credentials.
The most critical security headers include:
- Content-Security-Policy: Prevents XSS attacks by controlling resource loading
- Strict-Transport-Security: Enforces HTTPS connections
- X-Frame-Options: Protects against clickjacking
- X-Content-Type-Options: Prevents MIME type sniffing
- Referrer-Policy: Controls referrer information in requests
