This directory contains tests for the Async Cookies API.
A simple origin cookie is a cookie named with the
__Host- prefix which is always secure-flagged, always implicit-domain, always
/-scoped, and hence always unambiguous in the cookie jar serialization and origin-scoped. It can be treated as a simple key/value pair.
"LEGACY" in a cookie name here means it is an old-style unprefixed cookie name, so you can't tell e.g. whether it is Secure-flagged or
/-pathed just by looking at it, and its flags, domain and path may vary even in a single cookie jar serialization leading to apparent duplicate entries, ambiguities, and complexity (i.e. it cannot be treated as a simple key/value pair.)
Cookie names used in the tests are intended to be realistic. Traditional session cookie names are typically all-upper-case for broad framework compatibility. The more modern
"__Host-" prefix has only one allowed casing. An expected upgrade path from traditional “legacy” cookie names to simple origin cookie names is simply to prefix the traditional name with the
Many of the used cookie names are non-ASCII to ensure straightforward internationalization is possible at every API surface. These work in many modern browsers, though not yet all of them.
