##updated
def index
case params[:listing_type]
when "all"
#the key here is teh same key I used for
memcached
if stale?(:etag => 'all_posts_key')
@posts = get_all_post_from_memcached
else
head :not_modified and return
end
when "most_popular"
if stale?(:etag => 'most_popular_key')
@posts = get_all_most_popular_from_memcached
else
head :notified and return
end
respond_to do |format|
format.html
format.js #for ajax reqeusts
format.xml #for rss etc
end
update. I changed the original block a little and now get a double
render error what am I doing wrong, should "head :notified and return"
just return the header and not touch the respond_to block?
