Tips :
start with low request and high limits
observe..
increase request to request what needed in normal processing
lower limits to... what your strategy is. It can be 10% more than request for example or the same than request if you want to be safe
Little reminder
request field matching exactly "/myapi/foo/bar"
request.raw:"/myapi/foo/bar"
request field starting with "/myapi" :
request.raw:\/myapi\/*
request field end with foo :
request.raw:*.foo
Petite piqûre de rappel, ça ne fait pas de mal
