Problems accessing web server through ASA firewall - from inside interface to DMZ

We have a web server located in a DMZ which we cannot seem to reach via web browser from our internal network.  On one interface of our ASA 5520, we have an internal network (172.16.1.X) with security level 100 and on another interface, the DMZ (172.16.2.X) with security level 50.  The inside network has only the implicit rule to allow all traffic to less secure networks; it is NAT exempt to the DMZ segment.  We can ping the web server, and access it via RDP, but cannot see the web page via HTTP.  The web server is accessible from the internet, however, via either the IP address or the domain name.  I have attached a screenshot of the error message that IE gives when attempting to access the website via its internal (DMZ) address.

We have a Barracuda 310 inline with our firewall; this was unable to route to the DMZ network segment.  We gave it a static route (in the Barracuda interface) and now we're able to pass HTTP traffic.
