Thanks Chris, I will check it out. Yes I really don't want or need the load
balancing part, I just want our HTTP users to fail over if there is a
problem with the primary Domino server.
Thanks,

Puakma is "free for non-commercial use". You can download a full working
copy at their website. I'm not sure, though, if that copy has the
"failover-only" mode code if that's what you need.

All of my research says that it is for load balancing and failover.... steps from the help file include "Determines where replicas reside and whether they are marked out of service or pending delete. Checks the
server
availability index of each server that contains a replica. Checks the availability of the server by pinging the HTTP port or the HTTPS port, depending on the client request. Eliminates any servers that are not reachable or are RESTRICTED. Eliminates any servers that are BUSY or in
the
MAXUSERS state. Selects a server from those remaining. If there are no servers remaining, the ICM chooses a server that is BUSY or in the
MAXUSERS
state, if one is available. If there are multiple servers remaining, the ICM chooses the server with the lightest current workload". Fail over occurs: When a server fails, When an HTTP client is connected
to
a server that fails, the client receives a message saying that the
server
is not responding. To fail over to a different replica, if one is available, the user must contact the ICM again. The user can do this in
the
following ways: Click the Back button in the browser one or more times
to
connect to a page through the ICM: Use a bookmark: Type the URL The user may or may not have to reauthenticate with the new server. This
is
determined by the following factors: If the user already authenticated
with
the new server during this session, no authentication is necessary If
the
HTTP client and the server both support SSL3, reauthentication occurs automatically Do you remember what the cost is associated with Puakma's Web Booster?
We
are a small shop and would prefer not to spend a lot. We thought about
just
doing a DNS round robin, but then how do we handle the cache? We are a small shop, only about 550 mail databases, probably only around 200 web users. Maybe 100 web users and 200 Notes clients connected to
the
system at anyone time. Thanks, Scott Reece System Administrator City of Bend sreece@xxxxxxxxxxxxx Office - 541-388-4426 "Once you say you're going to settle for second, that's what happens to

Scott, I have seen a good bit of negative feedback with ICM. I have been
testing out Puakma's Web Booster. It will do load balancing/failover for
http. Actually, from my understanding, ICM will only do load balancing,
right? In my environment I don't want http to be load balanced because
our
cluster iSeries has a lot less horsepower. Puakma didn't initially have this, but they have since updated it to run in strict failover mode. I also know someone who is running a BlueCoat SG appliance for this. Also, I have not tested ICM personally, but when I was researching this last year I saw where customers didn't recommend ICM.

I would like touseit for our mail servers, but I also want to hear what anyone you think before I configure it. Is it going to be a performance hit to our mail servers? is it pretty seamless? What about the unread marks problems? please any feedback would be greatly appreciated, good or bad.
