[opencms-dev] Setting manual Content-Type header from a jsp

[Mike Dikan]

The property change worked like a charm, thanks Stephan.  However,  
since as I mentioned before, these files are coming over as a result  
of the built in synchronization process, and that process doesn't have  
support for properties, I'd like to try the approach you mention later  
in your message.  I see that the request/response are wrapped using  
CmsFlexRequest/CmsFlexResponse, but what i don't see is how to get at  
the flex controller using the request/response... Can you provide a  
little more detail on this step, and how it can be used to get at the  
top-level response to set the headers properly?
