HTTP::RangeSaver This is a helper class for updating an existing file with data from a partial content HTTP response. It understands both of the partial content formats defined in RFC 2616 (a single Content-Range header or a multipart/byteranges Content-Type). For convenience, it also handles complete content HTTP responses (status 200 or 203 rather than 206). PREREQUISITES libwww-perl (version 5.805 or better) INSTALLATION The usual four-stroke process: perl Makefile.PL make make test make install Testing doesn't require any kind of network connection since it uses synthetic HTTP::Response objects.
