I am assuming the following design:

browser
FIREWALL (BEGIN DMZ)
web server
FIREWALL (END DMZ)
app server/database server

You say it relies on the integrity of the network "beyond" the DMZ, but my 
point is that doesn't this design also rely on the integrity WITHIN the DMZ?  
Since SSL is ending at the web server here...traffic from the web server to the 
app server would be unencrypted...
