Mixed Content

Checks for HTTP resources on HTTPS pages


Rule ID	`security/mixed-content`
Category	Security
Scope	Per-page
Severity	error
Weight	7/10

Solution

Mixed content occurs when an HTTPS page loads resources over HTTP, breaking the security chain. Browsers may block these resources. Update all resource URLs to use HTTPS or protocol-relative URLs (//example.com). Check images, scripts, stylesheets, fonts, and iframes. Use Content-Security-Policy: upgrade-insecure-requests to automatically upgrade HTTP to HTTPS.
