Files in a zip file like
ephx_00_160.txt
in
http://virbo.org/ftp/users/ginet/CEASE-TSX-5/ephx_00.zip

should be accessible via

source=http://virbo.org/ftp/users/ginet/CEASE-TSX-5/ephx_00.zip
/ephx_00_160.txt

but if

source=http://virbo.org/ftp/users/ginet/CEASE-TSX-5/ephx_00.zip
/ephx_00_160.txt\nsource=http://virbo.org/ftp/users/ginet/CEASE-TSX-5/ephx_00.zip
/ephx_00_161.txt

is given, code should recognize that

http://virbo.org/ftp/users/ginet/CEASE-TSX-5/ephx_00.zip

is being downloaded. Access to ephx_00_161.txt should be made via expanded version of http://virbo.org/ftp/users/ginet/CEASE-TSX-5/ephx_00.zip

in

md5(http://virbo.org/ftp/users/ginet/CEASE-TSX-5/ephx_00.zip).zip/ephx_00.zip
