How should a server handle rate limiting for localhost connections?

A server must never block requests from localhost. Localhost requests are for local development and testing. Blocking localhost can stop a developer from working.

By Pawan Nayar · from the LLOS AI Learning record

The rule

A server must never block requests from localhost.

Localhost requests are for local development and testing. Blocking localhost can stop a developer from working.

A server should always allow localhost connections. Localhost connections are for the developer's own machine. These connections should bypass all rate limits. If a developer sees 'Too many requests' from localhost, there might be a problem. Possible issues include old running programs or incorrect network settings. A developer can fix this by restarting the server or resetting a concurrency lock.

A developer is testing a new feature on their local machine. The server has rate limiting enabled. If the server incorrectly applies rate limits to localhost, the developer cannot test the feature. The developer receives a 'Too many requests' error. This stops the developer's work.

How can a developer be sure the server is showing the correct version of a file after an edit?

A developer edits a file. The developer then needs to check if the server is actually using that new file.

How can a developer be sure the server is sending the most recent version of a file after an edit?

After a developer changes a file, the developer should test the server. The developer can use a command-line tool like `curl`.

How does a developer restart a server process correctly?

A developer must always restart the server after any file change. The developer should never tell a user to run the server.

How should a developer restart a server after making file changes?

A developer must restart the server after any file change. This makes sure the new code is used.
