I am trying to configure the load balancing of a remote cache server against multiple frontend instances.  I am using a Citrix Netscaler and have a rule that will load balance all lapi traffic, port 2099, coming from a virtual IP address on the netscaler to the two frontend instances.  I have another rule that load balances port 80 traffic and have a redirect rule on the netscaler so that all traffic to DNS entry http://livelink will be load balanced against the two frontend instances and all traffic from particular subnets, remote sites, will be redirected back to the RC server.  The issue I was having is that WebDAV would not function when the first frontend server is down.  I then set the Coserver port to static 12088, and reran the configure Remote Webserver, choose IIS and entered a virtual IP address that I had configured on the netscaler for another rule which is to load balance 12088, saved the .exe and ran it on the RC server.  Now when I try and use webdav it fails.  From the remote site if I use fiddler and try and edit a document within the Headers - Cookie for the webdav.webdavedit - there appear to be two extra entries xcache and xcacheUserName.  So I am not sure if the issue is the netscaler not passing through the correct headers or not having configured a host translation.  Has anybody had experience in this type of configuration? Thanks Nigel
