How to refresh cached object

I know this can be done with the cachemgr.cgi programme, but I am not to
eager to make that publically available due to the various issues of user
privacy etc.

Is there a symbol one can put in the url being fetched to inform the cache
to reget the object?

eg:

http://www.some.com.au/ <-- is a valid url

http://www.some.com.au/?reload <-- the ?reload is the symbol

I have no idea if this is doable this way.

Any ideas?

Regards and Salutations,

Mikel
