Overview

The HTTP Headers Analyzer is a professional utility designed to inspect web server responses, evaluate security configurations, and audit performance metrics by analyzing raw HTTP headers.

When to Use

  • •Verifying if security headers like Content-Security-Policy or HSTS are correctly implemented.
  • •Debugging connectivity or redirection issues by inspecting status codes and response headers.
  • •Auditing web server performance and caching behavior for optimization purposes.

How It Works

  • •Enter the target URL you wish to inspect and select the desired HTTP method.
  • •Customize your request by setting a specific User Agent if needed.
  • •Toggle the analysis options to include security, performance, and general response header data.
  • •Execute the request to receive a comprehensive breakdown of the server's response.

Use Cases

Security auditing to ensure compliance with modern web protection standards.
Troubleshooting site availability and redirect loops during deployment.
Optimizing cache control headers to improve website loading speeds.

Examples

1. Security Header Audit

Web Developer
Background
A developer needs to ensure their site is protected against XSS and clickjacking attacks.
Problem
Unsure if the server is correctly sending security headers like X-Frame-Options or CSP.
How to Use
Enter the site URL and ensure 'Include Security Analysis' is checked.
Outcome
The tool returns a list of active security headers, highlighting missing policies that need to be added to the server configuration.

2. Cache Performance Debugging

System Administrator
Background
Users are reporting that they see outdated content on the website.
Problem
Suspected misconfiguration of Cache-Control or ETag headers.
How to Use
Input the URL and run a GET request to inspect the caching-related headers.
Outcome
The analysis reveals an incorrect 'max-age' value, allowing the administrator to update the server settings to fix the caching issue.

FAQ

What information does this tool provide?

It provides a detailed breakdown of HTTP response headers, security policy status, performance timing, and general server response metadata.

Can I test POST or PUT requests?

Yes, you can select from various HTTP methods including GET, POST, PUT, DELETE, HEAD, and OPTIONS.

Does this tool check for SSL/TLS certificates?

The tool focuses on HTTP header analysis and security configurations sent by the server, rather than performing a full SSL/TLS handshake audit.

Why are some security headers missing?

If headers are missing, it indicates they are not being sent by your server, which may suggest a misconfiguration in your web server settings.

Is my data stored after analysis?

No, this tool performs real-time analysis and does not store your URLs or header data after the session is complete.
