Request Methods test page

Test page for making requests with the different request methods. Useful for checking if declarativeNetRequest requestMethods/excludedRequestMethods rule conditions are being matched correctly. Click one of the buttons to attempt a request, the latest result is displayed in the table.

Notes:

The Fetch API does not seem to support the CONNECT or TRACE methods, so those are disabled.
While the Fetch API allows free-form text for the request method, it doesn’t seem to uppercase non-standard request methods consistently. The “UNKNOWN” method is a test for this. (This web server will respond “400 Bad Request” if the request method isn’t uppercased.)
Browsers will often ignore the response body for HEAD requests.

Lowercase the request method string passed to the Fetch API?
