Subject Re: [users@httpd] way for me to turn off if-modified-since & always return 304 reply ?

Nope, there is no way you can prevent the client from sending you an IMS 
request. That is a browser prerogative, I suppose the best that you can 
do is bump up the Age and Expires headers that are returned along with 
the documents that your server delivers and hope that client browsers 
use that copy every-time.  Even with that if the user refreshes the 
page, most browsers end up sending an IMS.
