Workspace
Use HTTP Headers Checker
Connects to public services when you run a lookup
Browser security rules limit cross-origin access. If a website does not allow CORS, UTILORA reports that the result is unknown rather than incorrectly marking the site offline. Only HEAD requests are sent; no page body or cookies are collected.
BUILT FOR A SPECIFIC TASK
