Thanks Mike. Is there a way to remotely flush out the download cache?
Let's say I'm using an app that has web services where the reference
is defined to be dynamic, thus the url is in the app config file.
1000's of users have used the app and thus have the app config file on
their machine. The server is overloaded so IT decides to stick the web
services on another web server (a different url that can't be
redirected to for whatever reason). How can I flush out the 1000's of
users' download cache so the next time they hit the site it will go
and fetch the new config file?
