Subject Re: Http status code 302
Date Wed, 09 Jan 2013 14:12:31 GMT
Wire debugging with MCF 1.0.1 requires different logging.ini
parameters, because it uses commons-httpclient instead.  That's
described here:

http://hc.apache.org/httpclient-3.x/logging.html

I will need a working comparison to diagnose what is happening, so
please either get a log from curl, or better yet from MCF 1.0.1.

Thanks!
Karl
