I need to start serving large .PDF files from my ZopeHTTPServer. I'm thinking that I'd rather not put the actual data into bobo. Does anyone have an ExternalFile object? Also, I'd like to support byte-range serving. I'm thinking that I could modify Image.py File class, in index_html check to see if REQUEST has a byte-range heading, if so use a range on self.data, as in return self.data[startoffset:endoffset] I'd also have to set RESPONSE headers. I'm concerned about getLen and len methods. Are they used to set the content-length response header? If I set a content-length header myself will that over-ride Zope's default process of setting the length?
