I tried adding: response.headers['Cache-Control']="private" return response.stream(pdfContents,chunk_size=4096)
based on this thread: http://groups.google.com/group/web2py/browse_thread/thread/8da2043ec17debd6/4ae69758b19ba426 That solves the issue as well, without the need for patching main.py. I am still in the dark about why web2py seems to be streaming an HTML reply first... -- You received this message because you are subscribed to the Google Groups "web2py-users" group.
