 ### Step 4: Make the Internet Identity URL available in the build process.
 We want the sample application to integrate with Internet Identity differently depending on whether we deploy locally or on mainnet:
 
-- Locally the application should use the Internet Identity URL http://127.0.0.1:4943/?canisterId=<II_CANISTER_ID>.
+- Locally the application should use the Internet Identity URL http://<II_CANISTER_ID>.localhost:4943/.
 - On the mainnet it should use https://identity.ic0.app.
 
+> **Note**: If you are using Safari (or any other browser that does not support subdomains on localhost, i.e this URL `http://<II_CANISTER_ID>.localhost:4943/`), you can try to use the following URL instead: `http://localhost:4943/?canisterId=<II_CANISTER_ID>`. This will work for Safari but not Chrome.

 To do so, we can make an environment variable II_URL available using webpack.
