I am trying to send some dynamically generated binary data to the output buffer. How do I do it in python with Zope?

As I understand it HTMLFile(xxxx) returns a dtml document object. I could dump the data to file and then try to send it using the binary equivalent of the HTMLFile class. Is there such an animal?

I noticed there is the ImageFile class, but the guess_encoding module does not list the content type I need to publish. Is it a good idea to add mine there or can I override this?

Isn't there anyway I could just write to the output buffer?

The normal case is to just create a file object and manually enter the mime-type (called 'Content-type') in the edit form. If you are generating different binary data with an external method, just return it, and perhaps set some HTTP headers like so: def myDynamicContent(self, RESPONSE): "return dynamic binary data" # generate data RESPONSE.setHeader('content-type', 'foo/bar') # or whatever return data If you want to do this from DTML I think that you can use the return tag, or use RESPONSE.write. <dtml-call "RESPONSE.setHeader('content-type', 'foo/bar')"> <dtml-return data> or <dtml-call "RESPONSE.setHeader('content-type', 'foo/bar')"> <dtml-call "RESPONSE.write(data)"> Hope this helps. -Amos
