>IE8 だと
[PRE(JS example code)[
event.uri; // #session
]PRE]
で取得出来るのに対して、Fx3 だと、
[PRE(JS example code)[
event.domain; // #session
]PRE]
で取れるみたい。ただ HTML5 の spec 的には event.url が正解のようです。

>>If the script's domain contains no dots (U+002E) then the string ".localdomain" must be appended to the script's domain.

>file:///path/… とした場合は確かに使えないっぽいのですが、file scheme で使えないというわけではなくて、
file:///path/… というのは本当は file://localhost/path/… のホスト部分を省略したもので、後者の省略しない URL でローカルのファイルを開けば storage が使えます。(http と同様に、localhost.localdomain と指定する。)

- [11:03] <virtuelv> Hixie: would you support splitting the storage spec from HTML5?
- [11:04] <virtuelv> we have some use for the same interfaces in Widgets APIs and Events, and have some extra requirements, such as read-only storage, and the ability to reset storage to default values
- [11:12] <Hixie> yeah it'll be taken out, uh, *consults calendar*
- [11:13] * Hixie adds to the calendar
- [11:13] <Hixie> this month!
- [11:15] <virtuelv> Hixie: when you do, will you account for the extra requirements raised? (read-only storage items, reset to default (in Widgets, you can declare prefs in the manifest), and also making sure that it's agnostic towards where something is stored)?
- [11:16] <Hixie> i would recommend inheriting from the Storage interface and defining those extensions in the widgets spec
- [11:17] <jgraham> Hixie: Does that work better than making storage deal with both sets of requirements and making HTML5 say "all values are Read Write, All values default to undefined"
- [11:18] <Hixie> jgraham: i'll have to look closer at the two needs to know which is better
- [11:33] <Lachy> Hixie, are you splitting out localStorage/sessionStorage and the Database storage APIs together?
- [11:33] <Hixie> yes
- [11:34] <Lachy> ok, so basically the whole of section 5.11 "Structured client-side storage" will be removed
- [11:34] <Hixie> Lachy: right
- [11:38] <Hixie> Lachy: i'm tempted to leave them in the whatwg version (they'll still be in the whatwg source file...)
