## 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.

## Inputs

- **URL** (text): https://example.com
- **HTTP Method** (select)
- **User Agent** (text): Custom User Agent (optional)
- **Include Headers Analysis** (checkbox)
- **Include Security Analysis** (checkbox)
- **Include Performance Analysis** (checkbox)
- **Include Response Analysis** (checkbox)

## 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.

## Frequently asked questions

### 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.
