HTTP Header Extractor Examples

Review practical HTTP Header Extractor examples so you can understand expected input, output, and common patterns faster.

Why examples matter for HTTP Header Extractor

Use this HTTP Header Extractor to pull header lines from raw HTTP response text. It is useful when you copy a full raw response from logs, tools, docs, or terminals and want only the header section without the response body.

Example pages are especially useful for developer tools because they show what good input looks like, what kind of output to expect, and how the tool behaves in common scenarios.

HTTP Header Extractor examples

Extract headers from a simple response

Input

HTTP/1.1 200 OK
Content-Type: text/html
Cache-Control: no-cache

<html>Hello</html>

Output

HTTP/1.1 200 OK
Content-Type: text/html
Cache-Control: no-cache

Stops at the first empty line and returns only the header section.

Extract headers from a JSON response

Input

HTTP/2 404
Content-Type: application/json
X-Test: yes

{"error":"not found"}

Output

HTTP/2 404
Content-Type: application/json
X-Test: yes

Useful when the body is irrelevant and only headers matter.

How to use these examples

  1. Paste the raw HTTP response into the input box
  2. Click Run Tool to extract the header block
  3. Review the cleaned header-only output
  4. Copy the result for debugging, comparison, or notes
  5. Use another parser if you need deeper header analysis

Common mistakes in sample input

Only headers are pasted without a status line

Fix: That is still fine. The tool can return the lines it recognizes as the header block.

The raw text uses unusual formatting with no blank line before the body

Fix: Use a normally formatted raw response if you want clean separation.

The user expects a live fetch from a URL

Fix: This tool extracts from pasted raw response text, not from a live network request.

Next steps

After reviewing these examples, run the live tool with your own input. If your task involves a follow-up step, the related page can help you move to the next tool in the workflow.
