Hello, I am playing around with the new ExtFile product released a few days ago, in addition to a similar product I wrote myself. Both are exhibiting an unusual behavior. In the index_html method, I have: RESPONSE.setHeader('Content-Type', 'video/foo') RESPONSE.setHeader('Content-Length', 1212) Then, I return the file data. If I launch python and do: import Zope, ZPublisher ZPublisher.Zope('/path/to/myfile.mpg', d=1) I can trace the execution of these lines. The headers are set correctly in the response and, as far as I can tell, are returned correctly in the last statement my trace executed ("return response"). However, when I telnet to my web port and do: HEAD /path/to/myfile.mpg HTTP/1.0 I get: Content-Type: video/mpeg Content-Length: 0 Remember, I set content-type to video/foo, and length to 1212. These have been stepped on, I believe, by ZServer. I found this section in ZServer/medusa/default_handler.py: request['Last-Modified'] = http_date.build_http_date (mtime) request['Content-Length'] = file_length self.set_content_type (path, request) While I don't know, for sure, that this is what's causing my problem, it looks suspect to me. The curious thing is, using Zope's File object (defined in lib/python/OFS/Image.py), I get the correct Content-Length coming back. I did not check to see if Content-Type was overwritten or not. As far as I can tell, there is no difference in the way my code returns the file data versus the way Zope's File object does. Anyone know what's going on? --Jeff --- Jeff K.
