I've got a clickonce repository hosted on a Apache server ; for obvious reasons*, I don't want this repository to be cached by a proxy server.
I know there's no way to prevent a proxy to cache something if it wants to, but I'm looking for a way of either hinting the proxy not to cache my URL, or providing it with an "obsolescence date".
Is there a way to do that with Apache? If not, is it possible to do that with another webserver (IIS?)
If there are some options working only with some specific proxy vendors, I'm interested in those too.
** If the repository is cached, the software checks its version against an obsolete copy of the "latest version" (hold by the proxy) instead of checking itself against the "real" latest version, which is on my server.
