How to force browsers to clear cache?

What are the best ways to cache content over https in browsers?

• I have a situation like this. In my service users can create a business account for their organization and their employees as users, these authenticated users within that business account will read the same data again & again. consider these data are fetched from DFS. Can i make the requests cache-able by using "cache-control:private" directive, "max-age:for some reasonable time" control for expiry & "must-revalidate" control to validate the authentication to access the component. Or any other similar possibilities i can try to cache the requests which are being served through https.Will it have any security problems.

• Answer:

  For starters, check out http://blog.httpwatch.com/2009/01/15/https-performance-tuning/. Presumably, there's nothing "secure" about the static assets, and no reason not to cache them as aggressively as possible.
