How to use it
- Enter the domain or full URL whose headers you need.
- Select Check to make a header-only server request.
- Confirm Target Evaluated and Final Destination URL.
- Read each Header and Value row from the final response.
- Use Copy Result to copy the complete report.
The table contains only the final parsed header block. When the PHP request fails, the browser fallback supplies example headers rather than confirmed values.
What is the purpose of the tool
HTTP Header Checker exposes response metadata for a URL without downloading its body. It follows redirects and presents the final headers beside status and timing context.
Developers can use the rows to inspect content type, caching, server, security, and other directives. The page does not grade those settings.
What parameters it generates in output
| Field | Meaning | Healthy result |
|---|---|---|
| Target Evaluated | The normalized starting URL. | It is the intended resource. |
| Status badge | The final HTTP code and UI label. | The code is expected. |
| Latency | Total header-request time. | It meets the response target. |
| Redirects | The number of redirects followed. | The count is intentional. |
| Final Destination URL | The effective URL reached. | It is the correct resource. |
| Header | The name before a colon in the final header block. | Required headers are present. |
| Value | The trimmed content after the header name. | It matches the intended directive. |
FAQs related to that specific tool
Are headers from redirects included?
Only the last parsed header block is displayed after the server follows redirects.
Does the checker download the page body?
No. The cURL helper requests headers only.
Why are header names shown with their original casing?
The parser uses the names found in the final raw header block without normalizing them.
Why does the table say no custom headers received?
The response contained no parsed name-and-value lines or the request did not yield a usable final header block.
Can the fallback headers be trusted?
No. After a PHP failure, the browser inserts example server, content-type, HSTS, and nosniff headers.
Does this page grade security headers?
No. It lists headers but provides no security score or pass and fail analysis.
