Class: HTTP::CookieJar::HashStore

Defined in:
lib/http/cookie_jar/hash_store.rb

Overview

A store class that uses a hash-based cookie store.

In this store, cookies that share the same name, domain and path will overwrite each other regardless of the ‘for_domain` flag value. This store is built after the storage model described in RFC 6265 5.3 where there is no mention of how the host-only-flag affects in storing cookies. On the other hand, in MozillaStore two cookies with the same name, domain and path coexist as long as they differ in the `for_domain` flag value, which means they need to be expired individually.

#initialize(options = nil) ⇒ HashStore

:call-seq:

new(**options)

Generates a hash based cookie store.

Available option keywords are as below:

:gc_threshold : GC threshold; A GC happens when this many times cookies have been stored (default: ‘HTTP::Cookie::MAX_COOKIES_TOTAL / 20`)
