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 |

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.
