If set these variables to my own domain, does it prevent others from embedding my chatbot? The iframe already exposes the url, people can just copy the iframe code and embed my chatbot.

The CORS environment variables in Dify are used to set cross-origin access policies. Specifically:

• CONSOLE_CORS_ALLOW_ORIGINS: This sets the CORS policy for the console. By default, it is set to *, allowing access from all domains.
• WEB_API_CORS_ALLOW_ORIGINS: This sets the CORS policy for the web application. By default, it is also set to *, allowing access from all domains.

If you set these variables to your own domain, it will restrict access to only your specified domain, thereby preventing others from embedding your chatbot. For example:

CONSOLE_CORS_ALLOW_ORIGINS=my-frontend-domain
WEB_API_CORS_ALLOW_ORIGINS=my-frontend-domain

This configuration ensures that only requests from my-frontend-domain are allowed, preventing unauthorized embedding of your chatbot ^[1][2].

I already set them to my own domain. WEB_API_CORS_ALLOW_ORIGINS=https://riverhill.ai CONSOLE_CORS_ALLOW_ORIGINS=https://riverhill.ai But I can still embed the chatbot on other domains. I want to make sure the chatbot only works on my domain.

To ensure that your chatbot only works on your domain, you need to set additional environment variables beyond WEB_API_CORS_ALLOW_ORIGINS and CONSOLE_CORS_ALLOW_ORIGINS. Here are the steps you should follow:

1. Set the following environment variables to your domain:

export CONSOLE_API_URL="https://riverhill.ai/api/console"
export CONSOLE_WEB_URL="https://riverhill.ai/console"
export SERVICE_API_URL="https://riverhill.ai/api/service"
export APP_API_URL="https://riverhill.ai/api/app"
export APP_WEB_URL="https://riverhill.ai/app"

2. Ensure that WEB_API_CORS_ALLOW_ORIGINS and CONSOLE_CORS_ALLOW_ORIGINS are set to your domain:

export WEB_API_CORS_ALLOW_ORIGINS="https://riverhill.ai"
export CONSOLE_CORS_ALLOW_ORIGINS="https://riverhill.ai"

3. Add a check in your chatbot's code to verify the referrer domain. For example, if you are using Dify, you can use a utility function to check if the referrer is your domain:

export const isMyDomain = () => {
  return document.referrer.includes('riverhill.ai')
}

By setting these environment variables and adding a referrer check in your code, you can ensure that your chatbot only works on your specified domain ^[1][2].
