It doesn't by default. However, have a look at
http://www.djangoproject.com/documentation/templates_python/#django-core-context-processors-request
to see how to enable that. Generic views are given a RequestContext context,
so providing you enable the correct middleware processors, this will be
possible.
Once you have the "request" variable in your template, you can forget
about GET or POST. Just access the variable you want as an attribute on
the "request" (you can do this in Python, too). HttpRequest classes have
a __getitem__ method that allows you to treat them like a dictionary and
they will look for the variable in POST first and then GET.
