SafePlaywrightURLLoader validated only the initially submitted URL and then let the browser follow HTTP redirects and client-side navigations without re-checking them, so a public URL could redirect into the internal network (cloud metadata, RFC1918, loopback). Intercept document-type requests, re-run validate_url on each, and apply the same redirect policy as the requests loader (blocked unless AIOHTTP_CLIENT_ALLOW_REDIRECTS). Sub-resource requests pass through unchanged so page rendering performance is unaffected.
