Description From Tim Freeman 2007-04-16 13:55:55

Enhancement would allow a user to pull an image by generally available methods,
without installing GridFTP, allows for integration with online marketplaces
that support direct image download.  Should also be helpful with firewalls.

Added in TP1.2.3

Added implementation based on wget.  The target node (the image node in a
typical workspace deployment) is configured server side, i.e., not triggered by
target URL in staging request.

After the image has been downloaded, it can be verified using a provided md5 or
sha1 checksum.

This involves an interface change in the optional parameters schema, added
extra minOccurs=0 fields for the checksum and checksumtype.  Also made service
URL an optional field in that schema.

Added simple decompression option to the adapter:  only if file reports staging
target as gzip archive and it has a ".gz" suffix.  This can be disabled. 
Likely to change in the future.
