[gdal-dev] accessing zip files by URL

[Chaitanya kumar CH]

Joaguim,

I think /vsizip/vsicurl/http://path.to/the/file.zip works.

You have to initialize the zip file and remote file handlers using
VSIInstallCurlFileHandler() and VSIInstallZipFileHandler()

Refer: http://trac.osgeo.org/gdal/wiki/UserDocs/ReadInZip
