Gads, Eric, my brain isn't behaving this afternoon.  I told you
something wrong again.  I'm totally mixing up requests and allows. 
Maybe I'm trying to do too much at once.

The request line does indeed take a pattern, unlike what I told you in
my last message.  It's the allow line doesn't take a pattern - an
upstream site does not specify which products a downstream site can
receive.  It can only specify which feedtypes a downstream site can
receive.

And, the request line probably can't handle requests to *.hostname - it
probably wants just one hostname.  (In contrast, you can 'allow'
multiple hosts from a domain to connect using *.hostname.)

In the ldmd.conf that you sent, you have no requests to WSI.  You should
have one.  That is how WSI knows that you want to receive that data.

But, I see you have many allows for the WSI feed - are you feeding that
to downstream sites?  Is that ok for this proprietary data?  And, some
allows are for WSI - that's backwards.  I presume WSI does not want to
connect to you to receive the WSI data from you.

So, this may be the cause of the problem.  Add 

> request WSI ".*" sysu1\.uni\.wsicorp\.com

to the file, and take out

Keep the accepts in for now.  When things get working again, try taking
them out and see if things still work.

Eric, I'm very sorry for the confusion I've introduced this afternoon. 
I hope you can bare with me.
