Is it possible to have the following deployment architecture for hosting SharePoint internet websites? If yes, how can I make the front-end web servers as read-only while allowing content modifications on a server behind DMZ through internal network?
2 x Front-end Web Servers in read-only mode (No content modifications allowed via internet).
Tier-2: 1 x Back-end Web Server where content managers update and publish content via internal network.
1 x Application Server with Central Administration + Indexing Service
Tier-3: 2 x Clustered Database Servers
