This is a special URL patterns replacement that prevents caching of any URL listed within it. We needed this in Review Board to prevent the JSON API function results from being cached in Internet Explorer.

How is that better than the following code: urlpatterns = patterns('', (r'foo/$', never_cache(myview)) )
buriy: less code. Just as different as to use patters('common.prefix', ...)
Yeah, I basically didn't want to have to put never_cache() around every single URL entry for my site's JSON API (of which there are 30 or so functions). Much easier to do it once and never touch it again.
