request.write is for writing the body of the request, not the headers. 
To affect the headers, see below.

Override render_GET, and then call setHeader('content-type', 
'application/x-shockwave-flash'). There may also be some sort of 
attribute you can set which will cause FilteredScript to do this for 
you, I'm not sure. Examine the source code.
