Based on your understanding of CAS redirection, could you please examine the following scenario and answer the question at the bottom. Thank you.
Two sites each with internet facing CAS and mailboxes. External URL for all internet facing CAS servers is the same: OWA.COMPANY.COM. DNS round robin is used to load balance connectivity to the CAS servers at each location.
If a user is DNS directed to the a CAS server in SITE_A but his mailbox is in SITE_B, it appears, based on the article, that the user would be redirected and given the internet facing URL of a CAS server in SITE_B. However, since SITE_A and SITE_B both have the same internet facing URL, the user could get trapped since his DNS entry may not round robin because of a cached DNS entry.
Is CAS smart enough to proxy this request since all external URL's are the same? If not, can redirection be disabled and how?
