Is HTTP 200 always cached by browsers?

Not necessarily. Caching depends on the presence of HTTP response headers such as Cache-Control, ETag, and Last-Modified.

Can an HTTP 200 response contain error messages?

Yes, this is an anti-pattern known as a 'soft 404'. If a server returns an error page or 'Page Not Found' message with a 200 status code, search engines may misinterpret it as valid content.

How do I check the HTTP status code of a URL?

Use our online HTTP Header Checker tool or run 'curl -I ' from your terminal.

Common Causes & Triggers

The requested URL matches a valid server route or static file.
The client submitted valid headers and authentication credentials.
Database queries and application logic executed without errors.

Troubleshooting & Resolution

Verify response headers such as Content-Type and Content-Length match client expectations.
Ensure proper Cache-Control headers are configured to prevent stale data delivery.
Monitor response payload sizes to optimize Time to First Byte (TTFB).

Search Engine (Googlebot) SEO Impact

Optimal. Search engine crawlers (Googlebot, Bingbot) expect 200 OK responses to discover, crawl, and index web pages.

Inspect via Terminal (cURL)

Execute this command to inspect headers and response codes from your terminal:

curl -I https://example.com
