[Swift-user] mapper for internet resources

You can write files to any gridftp server by mapping to a gsiftp:// URI, 
as with input.

As far as I understand, the gsiftp provider can support: http, https, 
ftp, and gsiftp URIs, with the gridftp data provider, <gridftp> in 
sites.xml.

If the uri works with globus-url-copy I think it will work with the 
gridftp provider.

I think that Swift can also accept other providers from the CoG toolkit, 
such as scp and webdav. See
   http://www.ci.uchicago.edu/swift/guides/userguide.php#id2745803
for using scp.  We should test and document hos to use webdav.

Perhaps Mihael or Ben can verify and clarify the above.
