[LON-CAPA-users] connection issue re library server

Wed, 2 Mar 2005 08:39:52 -0700

Jim,

I've seen similar issues before, typically traced to peer-to-peer sharing 
software.  LON-CAPA makes extensive use of re-directed web pages.  For 
technical reasons I don't understand, apparently some sharing software such 
as kazaa and the like wreak havoc on these redirects.  If she recently 
installed, or upgraded similar software that could be the issue.  There have 
been some threads on this in the past, but I can't find them at the moment.
