Application Request Routing (ARR)
Does ARR guarantee session stickness?

I have a question regarding ARR. Here is the deployment we would like to have. We have multiple IIS servers(sharing load) installed inside corporate firewall and ARR inside the DMZ. Our customers use web browsers to connect. We would like ARR to act as both
load balancer and reverse proxy to forward client requests to our IIS servers. However, we require the same browser session be forwarded to the same IIS server. Can ARR do that? I think it should. But I just want to confirm it.
Thank you very much for your help!

we use this in our webfarm setup and have run into an issue where the host name is no longer load balanced. ARR affinitizes website to one server - subsequent connections are then routed to one server - as the load increases on this server and slows down
the website for all clients ARR does not send newer connections another server in the webfarm.
is there a performance setting we can use to route new requests for an affected website to all the other servers in the farm? while still maintaining 'sticky' sessions to the original server? and maintain 'sticky' sessions to any other server?
