Configuring ZCS HTTP Proxy
In addition to IMAP/POP3 proxying, the Zimra proxy package based on nginx is also able to reverse proxy HTTP requests to the right backend server.
Using an nginx-based reverse proxy for HTTP helps to hide names of backend mailbox servers from end users.
For example, users can always use their web browser to visit the proxy server at http://mail.example.com. The connection from users whose mailbox lives on mbs1. example.com is proxied to mbs1.example.com by the proxy running on the mail.example.com server. In addition to the ZCS web interface, clients such as REST and CalDAV clients, Zimbra Connector for Outlook and Zimbra Mobile Sync devices are also supported by the proxy.
HTTP reverse proxy routes requests as follows:
*
If the request has an auth token cookie (ZM_AUTH_TOKEN), the request is routed to the backend mailbox server of the authenticated user.
*
*
