What does HTTP Request Tester actually do?

The HTTP tester sends a request to a URL you choose and shows the status, headers, and body the browser was allowed to read. The request leaves your machine. CORS may hide the body even when the server responded. DevTooKit does not proxy the call for you.

When should I use HTTP Request Tester?

Use it to poke a public endpoint while you look at status and headers.

When should I not use HTTP Request Tester?

Do not assume a CORS failure means the server was down.

What does HTTP Request Tester not do?

Browsers attach CORS rules. This is not curl. Credentials and private IPs are your responsibility.
