Symfony2: 2.0 RC1 released

I tried out Symfony (1.x) and I'm thankful for it. It's madness drove me to Rails, where I built some amazing stuff with! It was the entry drug that brought me over from php to the great (but at first sight scary) land of Ruby.

I like both codeigniter &#38; cakephp.<p>codeigniter is super easy and joy to work with. 1&#62; simple 2&#62; great documentation (most amazing docs i have seen so far) + forum 3&#62; you can not go wrong , its so easy to write apps using it<p>cakephp because of 1&#62; "bake" utility to generate code from looking at table 2&#62; easy to access database using models classes 3&#62; built in auth component (and few other components at cake bakery)<p>never needed to look at anywhere else ;)

HTTP cache seems to be an important part of Symfony2. Does anyone have experience with that? (either in Symfony or another framework)<p>Is that the preferred caching method these days?
