[support] Memcache and JS

We have a D6 site that we were using Memcache on. Various JS things, such as Views UI and attachment uploads, are failing with "HTTP error 0." If we disable Memcache the errors go away. I don't see anything terribly helpful on D.O. Has anyone encountered this? How did you get around it?   Nancy Injustice anywhere is a threat to justice everywhere. -- Dr. Martin L. King, Jr.
