Avoid 301 redirect caching www

some browser cached www.somesite.com url, need available somesite.com url case exist subdomain like city_name.somesite.com and www. is url of main city.

Users use somesite.com , but browsers cache www. and users always receive main city..

response headers inf: Cache-Control:no-store, no-cache, must-revalidate, post-check=0, pre-check=0 Expires:Thu, 19 Nov 1981 08:52:00 GMT Pragma:no-cache

can't use 307 redirect, any ideas?
