While zip-path could support relative addressing outside of a zip, it's not clear whether this is desirable.

URLs

name example nested zips relative URLs pointing outside zip
sub-scheme zip:http://example.org/test!image.jpg zip:zip:/test!inner.zip!image.jpg - (zip base URL is zip:/.../)
zip-path http://example.org/test%!image.jpg ("%!" as separator) /test%!inner.zip%!image.jpg √ ../otherimage.jpg
zip-path #2 http://example.org/test.zip!image.jpg (".zip!" as separator, but request path includes trailing ".zip") /test.zip!inner.zip%!image.jpg √ ../otherimage.jpg
fragment http://example.org/test#image.jpg http://example.org/test#inner.zip!image.jpg (??) - (zip base URL is zip:/.../)

While zip-path could support relative addressing outside of a zip, it's not clear whether this is desirable.

Format

For http://fetch.spec.whatwg.org/#zip-archives we need to document the zip format. Either through reference to the PKWARE text, or via a new standard (XKCD-style).

Gecko

baku https://mxr.mozilla.org/mozilla-central/source/dom/file/ArchiveZipEvent.cpp
baku https://mxr.mozilla.org/mozilla-central/source/dom/file/ArchiveZipFile.cpp
baku so the first file (line 120~)
baku reads the file and creates ArchiveZipItem for each file contained in the archive
baku ArhiceZipFile implements a nsIInputStream and what it does is the reading of the content.
baku you have an ArchiveZipFile for each file.

PKWARE
