子域的HTML 5本地存储大小限制
HTML5的localStorage数据库受大小限制。每个域的标准大小为5或10MB。建议每个来源限制为5MB。
陈述以下内容-
User agents should guard against sites storing data under their origin's other affiliated sites, e.g. storing up to the limit in a1.example.com,a2.example.com, a3.example.com, etc, circumventing the mainexample.com storage limit.
对于大小限制-
A mostly arbitrary limit of five megabytes per origin is suggested. Implementation feedback is welcome and will be used to update this suggestion in the future.
