HTTP Header Checker – View Website Response Headers Easily

Understanding how a website responds to an HTTP request is crucial for developers, SEO experts, and digital marketers. With our HTTP Header Checker tool, you can quickly view HTTP response headers for any website in a clear table format. No technical skills required.

What Are HTTP Headers?

HTTP headers are metadata exchanged between a web browser (client) and a web server. These headers provide essential details about the HTTP request and response such as:

• HTTP status codes (e.g., 200 OK, 301 Redirect)
• Server type
• Content type and length
• Cache control
• Security policies
• Redirect locations

Headers can appear in both request and response formats. Our tool focuses on response headers, which tell you how the server handled your request.

Why HTTP Response Headers Matter

Whether you're troubleshooting a website or optimizing for SEO and performance, HTTP headers offer insights like:

• Is the site redirecting properly?
• What server software is being used?
• Are the correct MIME types being returned?
• Is the site using HTTPS and secure headers?
• How long are resources cached?

These headers influence browser behavior, security settings, and even search engine indexing.

Common HTTP Response Headers

Here are some of the most common HTTP response headers and what they mean:

• Status Code: Indicates if the request succeeded or failed (e.g., 200 OK, 404 Not Found, 301 Moved Permanently)
• Content-Type: Tells the browser what kind of content to expect (e.g., text/html, application/json)
• Server: Shows the software used on the server (e.g., Apache, Nginx)
• Cache-Control: Determines how long the content should be cached
• Location: Used in redirects to point to the new URL
• Strict-Transport-Security: Instructs browsers to only use HTTPS connections
