Frequently Asked Questions
What are HTTP headers?
HTTP headers are key-value pairs sent between a web browser and a server. They transfer metadata regarding requests and responses, detailing content types, encoding, cookie configurations, and caching rules.
Why are HTTP security headers important?
Security headers tell modern web browsers how to protect users from common vulnerabilities like Cross-Site Scripting (XSS), Clickjacking, and packet sniffing. Setting them correctly is a core DevOps best practice.
Can this tool check local addresses?
No. This tool runs from Pingzo serverless nodes, meaning it can only check publicly accessible domain names and URLs. Local addresses (like localhost or 192.168.1.1) cannot be scanned.
