Comment (by Daniel Pope <[EMAIL PROTECTED]>):
Restricting this to a subset of the GET parameters would only reduce the
number of duplicate copies in the cache. As such I think it's more
beneficial to provide transparent caching with a simple decorator API. The
reason we need to use {{{request.get_full_path()}}} is that the current
behaviour allows Django to serve the wrong page for requests with a query
string. Trying to reduce the number of duplicate entries in the cache to
the bare minimum is more of a wishlist item.
Rather than building all of the possible ways you could generate cache
keys into decorators, why not just allow {{{cache_page}}} to take a
callable?
eg.
{{{
@cache_page(key=lambda request: request.path)
def slashdot_this(request):
...
}}}
This should still default to {{{request.get_full_path()}}} so that the
default behaviour works for all views.
