As a developer when working with APIs, troubleshooting HTTP responses, or optimizing server performance, response headers<\/a> can tell you a lot from content type and caching rules to redirect info and rate limits. While browsers hide most of this behind DevTools, cURL gives you full, direct access from the command line<\/strong>.<\/p>\n\n\n\n

If you\u2019ve ever wondered how to view HTTP headers using cURL<\/a><\/strong>, the good news is it\u2019s just a matter of using the right flags<\/strong>. But which flags show headers only, which include the response body, and which let you debug both request and response?<\/p>\n\n\n\n

In this article, we\u2019ll break down the different ways to view response headers with cURL, how to save them, and when to use each approach whether you\u2019re debugging an API call or just checking if a CDN is doing its job.<\/p>\n\n\n\n
