Subject RE: how to push in Apache

himself via cgi and a back end server.  His question is "can he push a page to 
the browser (who has not requested one) when the person is internally 

I suspect not and do not understand why the person just does not get a 
"disallowed" page from the cgi process instead of trying to push a page.
