Hi Doug, 1) I'm not quite sure about the question, but your session is also backed by beaker. By default the backend of session is filesystem.
2) Expiring @beaker_cache explicitly is a little tricky. You'll need several things: from pylons import cache, request from pylons.decorators.cache import create_cache_key See below example: key_dict = request.GET.mixed() namespace, key = create_cache_key(YourControllerClass.controller_method, key_dict) cache.get_cache(namespace).remove(key) 3) Most people I know, including me does it in the controller layer. I think it's the most explicit way of doing it. 4) It depends on how you structure the cache keys. 5) You can define multiple cache regions for different type of users. Below is example on how you can configure it: beaker.cache.regions = model beaker.cache.model.type = ext:memcached beaker.cache.model.url = 127.0.0.1:11211 Don't worry about asking questions here, besides: "There are only two hard problems in Computer Science: cache invalidation and naming things." -- Phil Karlton Cheers, Didip Kerabat On Wed, Jul 7, 2010 at 1:35 PM, writeson <[email protected]> wrote: > Hi all, > > I'm building Intranet Pylons applications at work and need some help > understanding caching.
