latch-method

latch-method

HTTP latch that decides each request by its method.

The decision for each method is read from wasi:config/store. The key is the lowercase method, e.g. get or post, the value is deferred or denied. A method without a key uses the * key, and is deferred without it. A denied request fails with http-request-method-invalid.

get=deferred
head=deferred
*=denied

Every value must be deferred, an empty value, or denied. Otherwise the cause is logged at the critical level and every request fails with an invalid-config<latch-method> latch error, so a typo is noticed rather than ignored:

Invalid config LATCH=latch-method KEY=post VALUE=maybe ERROR=expected one of: 'deferred', 'denied'
