I have successfully used the CSS to load-balance an application in our network for some time. I have just added to the configuration to allow load-balance of new Microsoft Exchange Servers. It appears that the load-balancing works for Microsoft Outlook users but "not" for Microsoft OWA users. It appears that Microsoft OWA users cannot get to the site when the rules are active. We cannot find in Cisco docs what we are missing. I have included my configuration below. Any help is really appreciated. Thanks. Lisa

See if you have inserted the text string. The primary purpose of text string insertion in the HTTP header to a back-end server is to support Microsoft Outlook Web Access (OWA) applications.
