How to direct traffic based on URL

[Max Michaels]

Hey Brad,

Thanks again for your help. We here at del.icio.us owe ya one. So I've 
made a little progress and now the problem I'm running into is that 
when i request the pages. It is directing correctly to the vhosts, but 
it is saying that the vhosts aren't defined. I'm getting a 404 with the 
message "Not Found (no configured vhosts 'delicious')" or 
delicious_rss. I'm thinking that from looking at the example vhost 
config that vhosts aren't aware of Pools. Just a guess. My config is 
below. Thanks again for your help.

oad DeliciousSelector

CREATE POOL delicious_rss
         POOL delicious_rss ADD x.x.x.x6:80

CREATE POOL delicious
         POOL delicious ADD y.y.y.y:80

CREATE SERVICE balancer2
   SET listen          = z.z.z.z:80
   SET role            = selector
   SET plugins         = DeliciousSelector
ENABLE balancer2


Thanks again,

-max
