Re^2: Fetch URL Contents to File Handle

A ZIP file's central directory is at the end of the file. Although you could get fancy with range requests, ...

This is true, but it is also possible to read a zip file in streaming mode without using the central directory at the end of the file. That's what IO::Uncompress::AnyUncompress does (via IO::Uncompress::Unzip).

If there is a HTTP module that exposes a filehandle interface, then IO::Uncompress::AnyUncompress can read it.

My understanding is that it's possible for files to have been deleted or replaced in the central directory but still be present in the ZIP file, but I haven't encountered such a ZIP file in the wild myself. I did write the parent node before I had looked into the ZIP file in question to discover that it only contains a single file.	[reply]
