Frequently Asked Questions
What is an HTTP Status Code?
It's a standard response code given by web servers. 200 means OK, 301 is a permanent redirect, 404 means not found, and 500 is a server error.
Why are headers important?
Headers control caching, authentication, cookies, and connection management. They are critical for security (e.g., CSP, HSTS) and performance.
What is a 301 Redirect?
A 301 redirect signals to search engines that a page has permanently moved to a new location. It passes "link juice" (ranking power) to the new URL.
