Server Headers Checker – Analyze HTTP Response Headers Instantly

Advanced Server Headers Checker Tool for Developers and SEO Professionals

We have a top-notch Server Headers Checker tool. It checks HTTP response headers in real-time. It's key for developers, system admins, SEO experts, and security pros to see how servers talk to clients.

Our tool shows everything from cache policies to security settings. It uncovers all the details of server communication.

What Are Server Headers?

HTTP response headers are data sent between a server and a client when you visit a webpage. They control how content is delivered, stored, redirected, or kept safe.

Some important HTTP headers are:

  • Server

  • Content-Type

  • Content-Encoding

  • Cache-Control

  • Location

  • X-Frame-Options

  • Strict-Transport-Security

  • Set-Cookie

  • Content-Security-Policy

Features of Our Server Headers Checker Tool

✅ Instant Header Retrieval

Our tool quickly gets the full HTTP response headers of any URL. It includes:

  • HTTP/1.1, HTTP/2, or HTTP/3 response codes

  • All relevant response headers

  • Redirect chains (up to 10 hops)

✅ Redirect Chain Visualization

We show the full redirect paths. This includes status codes (301, 302, 307, 308) and intermediate URLs. It helps with debugging and SEO insights.

✅ Security Header Analysis

Get detailed info on HTTP security headers like:

  • Strict-Transport-Security (HSTS)

  • Content-Security-Policy (CSP)

  • X-Content-Type-Options

  • X-XSS-Protection

  • X-Frame-Options

  • Referrer-Policy

We point out missing headers and offer advice.

✅ Cache Policy Evaluation

Check cache directives to see:

  • Content freshness

  • CDN behavior

  • Resource revalidation (ETag, Last-Modified)

Why HTTP Headers Matter

Header Function Importance
Content-Type Declares file type (e.g., text/html, application/json) Prevents misinterpretation of content
Server Discloses server software Useful for diagnostics but should be obfuscated
Location Handles redirects Critical for SEO and user routing
Cache-Control Sets browser cache policy Boosts performance
Strict-Transport-Security Enforces HTTPS Enhances security
Set-Cookie Manages session and user data Affects stateful browsing
Content-Security-Policy Prevents XSS attacks Essential for modern web security

Full Redirect Chain and Status Code Display

Easily detect:

  • Redirect loops

  • Improper 301 vs 302 usage

  • Mixed protocol redirection (HTTP to HTTPS or vice versa)

Each redirection displays:

  • Status code

  • Final and intermediate URLs

  • Header differences across hops

How Our Tool Supports SEO Optimization

? Validate Canonical Redirection

Make sure your site correctly redirects http:// to https:// and www to non-www (or vice versa) using 301 redirects.

? Confirm Cache and Compression

Headers like Cache-Control, ETag, and Content-Encoding: gzip help improve performance and Core Web Vitals scores.

? Improve Security Posture

Check for essential HTTP security headers. Not having headers like X-Frame-Options can make your site vulnerable to clickjacking.

API Integration for Developers

Use our RESTful Server Headers API for automated checks:

  • Endpoint: /api/header-check?url=

  • Returns: JSON payload with all response headers and redirect data

  • Includes: timestamp, TTL, status code, header metadata

Great for CI/CD environments and automated monitoring tools.

Request headers are sent by the client (browser). Response headers are returned by the server. They provide metadata about the resource or server behavior.

Can I test non-200 status codes?

Yes. Our tool shows complete headers for 3xx, 4xx, and 5xx responses.

Does it support HTTPS and HTTP/2?

Yes, our checker works with all modern protocols. This includes HTTPS, HTTP/2, and HTTP/3.
