[webservices] restricted data

[Philip Crotwell]

Hi John

I have put up a tarball that handles the proxy for a dataselect style
web service to a DHI seismogram server to allow access to restricted
data. See the ReadMe in the tarball for how to use it.

http://www.seis.sc.edu/~crotwell/dataselectDHIProxy/

All a bit rough, but seems to work for my limited testing. Not bad for
a couple of hours in the morning.

You might want to look at bit at this to see how it is done in SOD,
which is closely related to this code:
http://www.seis.sc.edu/sod/documentation/restricted.html

Enjoy, and let me know if you find any issues.
Philip

We needed a new paradigm in which a users' personal password will give them access to all the data sets they are allowed to access.  At the same time we modernized the internal password management at the DMC.  A message has been drafted explaining the details to those users with restricted data sets, but in short you'll be able to use the same data web services and provide a username and password to get access to your data.  HTTP Digest Authentication will be used, it's standard and well supported by nearly all HTTP clients/toolkits.
