🌐 HTTP Header Viewer – Inspect and Analyze Website Headers Instantly
📘 Introduction
HTTP headers are the hidden messengers of the internet. Every time you visit a website, your browser and the server exchange metadata through these headers — defining how pages load, what type of content is sent, and how your data is cached or secured. Solvezi’s HTTP Header Viewer helps you decode this information effortlessly.
This tool is perfect for developers, SEO professionals, and cybersecurity experts who want to understand website behavior, debug APIs, and enhance web performance and security.

🧭 What is an HTTP Header Viewer?
An HTTP Header Viewer is a web-based tool that lets you see the headers sent between a browser (client) and a web server. These headers contain important information like the content type, caching policies, cookies, server software, and more.
For example:
| Header Name | Example Value | Description |
|---|---|---|
| Content-Type | text/html; charset=UTF-8 | Defines the media type of the response. |
| Server | nginx/1.18.0 | Shows the server software handling the request. |
| Cache-Control | no-cache, no-store | Defines how responses are cached. |
| Set-Cookie | sessionId=abc123; Secure; HttpOnly | Manages user sessions. |
| Strict-Transport-Security | max-age=31536000; includeSubDomains | Forces browsers to use HTTPS only. |

🧠 Understanding HTTP Headers
HTTP headers are divided into two main types:
- Request Headers: Sent from the client to the server (e.g.,
User-Agent,Accept,Authorization). - Response Headers: Sent from the server back to the client (e.g.,
Content-Type,Server,Cache-Control).
These headers work together to manage communication between both sides — defining how content is delivered, secured, and cached.
🧩 Common Header Categories
| Category | Examples | Purpose |
|---|---|---|
| General Headers | Date, Connection | Apply to both requests and responses. |
| Request Headers | Accept, User-Agent, Host | Sent by the browser with each request. |
| Response Headers | Server, Set-Cookie, Content-Length | Returned by the server to describe the response. |
| Entity Headers | Content-Type, Content-Encoding | Provide details about the content itself. |
