Can I prescribe update for proxy server?

[Erik Kullberg]

I manage a home page, the purpose of wich is to keep available certain
information, wich may change. Some of the readers are sitting behind a proxy
server. Sometimes they do not observe that I have updated the information
until it's too late, since their proxy server does not update frequently
enough.

Can I influence this via my html code?
