How do I troubleshoot CORS issues in my Rack application?
An example of an AI chatbot conversation about troubleshooting CORS in Rack applications.
I'm having trouble with CORS in my Rack application. Can you help me troubleshoot?
Of course! What specific CORS error are you encountering?
I'm getting a 'No 'Access-Control-Allow-Origin' header is present on the requested resource' error.
This usually means that your server isn't configured to allow requests from the origin you're using. Have you set the appropriate headers?
I haven't. How do I set those headers in my Rack app?
You can use the Rack::Cors middleware. You'll need to add it to your Gemfile and configure it in your application.
