Re: Ideas on forwarding things around in Cherokee

Good idea as always Stefan.
We use Varnish primarily at this point to cache data from 3rd party
providers. We do this because the 3rd pary data we serve out is
highly predictable, mostly static in nature - things like weather
forecast - which is fine to update just once every x hours. No need to
have multiple requests for the same document going to 3rd party over
and over. Stuff like RSS feeds are also very much cacheable for
defined periods of time to reduce artificial load of repetitive
requests.
Varnish has advanced configuration features for caching that we aren't
using currently - as we are too busy with other projects to implement
and test. The performance of Varnish is pretty fast when data is
cached. In small tests we've done, even faster than Cherokee with
same data cached.
Varnish allows for custom configurable cache time based on filetype.
It also allows custom redirection for authentication and various other
in-line request munging of data and the request and ability to flush
the request out anywhere in-line where certain conditions met in your
config file.
Of course once Cherokee launches caching for proxy I suspect we will
stick with Cherokee only solution :)
