How to direct traffic based on URL

[Brad Fitzpatrick]

I should've changed the error message.  Replace in your head "configured
vhosts" with "configured service".

You need to make two services (named delicious and delicious_rss) of type
reverse_proxy, setup with all the fancy options you desire, and then have
delicious use pool, say, "pool_regular" and delcious_rss service use pool,
say, "pool_rss".
