What are some tips for debugging CSP issues?

Debugging Content Security Policy (CSP) issues can be tricky. Here are some tips: 1. Check the browser console for CSP violations. 2. Use the report-uri directive to log violations. 3. Simplify your policy to identify problematic directives.

How can I use the report-uri directive effectively?

The report-uri directive allows you to specify a URL where the browser can send reports of CSP violations. Set up a server endpoint to receive these reports and analyze them to understand which resources are being blocked.

What tools can help me analyze CSP reports?

You can use tools like CSP Evaluator, Report URI, or your own custom logging solution to analyze CSP reports. These tools can help visualize violations and suggest policy adjustments.

Are there common mistakes to avoid when setting up CSP?

Yes, common mistakes include overly restrictive policies that block legitimate resources, forgetting to include necessary directives, and not testing policies in different browsers.
