Server Headers Examination - Analyze the HTTP Headers of a Website

Our HTTP header examination tool allows you to input any domain name or URL to inspect its HTTP response headers. These headers provide crucial information, including the security policies in place for the website and the total caching duration.

The information contained within the HTTP headers is vital for network administrators and developers, as it aids in assessing the performance and security of a website.

How to Utilize Our HTTP Header Examination Tool

Follow these simple steps to use our server header examination tool to check the HTTP headers of any domain:

  1. Launch the HTTP header examination tool and click on the input field located in the center.
  2. Enter or paste the domain name you wish to analyze.
  3. Click the blue button labeled “Check HTTP Headers.”
  4. Wait a few moments for the process to complete, then scroll down to view all the details.

Our header examination tool is user-friendly. There are no complicated procedures to follow, and you won’t need to input any intricate lines of code. Just specify the domain name, and our tool will take care of the rest.

Overview of Common HTTP Headers and Their Interpretations

When you examine the HTTP headers of a URL, you may encounter the following values along with their meanings:

  • Accept: Indicates the types of content the client is capable of processing.
  • Accept-Charset: Specifies the character encoding methods that the client can understand.
  • Accept-Encoding: Details the content encoding methods that the client can process.
  • Authorization: Contains credentials and information for authentication.
  • Cache-Control: Defines the server's caching strategy for managing client requests and responses.
  • Connection: Indicates whether the connection between the server and client remains open after a transaction.
  • Content-Encoding: Describes the encoding transformations applied to the body (e.g., gzip).
  • Content-Language: Specifies the natural language of the content.
  • Content-Length: Displays the size of the request/response in bytes.
  • Cookie: Sends cookies stored on the client to the server.
  • Date: Shows the date and time of the message (request/response).
  • ETag: A unique identifier for a version of a resource used for cache validation.
  • Expect: Describes the expectations the server must fulfill to process the request.
  • Host: Specifies the domain name of the server (used in virtual hosting).
  • If-Modified-Since: Requests content only if it has been modified after a specified date.
  • If-None-Match: Requests content only if the ETag does not match the cached version.
  • Origin: Identifies the origin of a cross-origin request (CORS).
  • Referer: Provides the URL of the referring resource.
  • Server: Contains information about the server software handling the request.
  • Set-Cookie: Instructs the client to store a cookie.
  • Transfer-Encoding: Specifies the encoding method used to safely transfer the payload.
  • User-Agent: Contains information about the client software making the request.
  • WWW-Authenticate: Indicates the authentication methods required by the server.

Frequently Asked Questions

Why is it important to check the HTTP headers of a URL?

Checking the HTTP headers of a URL is essential to ensure it responds appropriately to client requests. The headers provide valuable insights into how the URL responds to incoming requests and the types of requests it is designed to handle.

What does HTTP/1.1 301 Moved Permanently signify?

This status indicates that the URL has been permanently relocated to a new address. When using our header examination tool, it will first display the error, informing you that the URL has been moved, and subsequently show you the headers of the new URL.

What should I do if I don’t receive any results for the entered URL?

If you do not see any results for the entered URL, double-check the address to ensure it is correct. If the headers are still not displayed, try again later to eliminate any temporary issues with the tool.
