We've recently started using an online work order system called Maintenance
Direct by schooldude.com. It's hosted by them. We are having a problem
with pages loading blank until they are refreshed and then coming up fine.
It happens to almost every page.

We are running BM3.8.4 on NW6.5..4.
In nwadmin, I've set schooldude.com, www.schooldude.com, *.schooldude.com,
and the ip addresses of the servers to not be cached under the "Cache Object
Control" I then unloaded and reloaded the proxy with -cc and the pages
still have to be refreshed. What might I have wrong?
