I have been trying to get a test routine working that uses RESPONSE.write... without success:
1) RESPONSE.setHeader() affects the RESPONSE object. But that does not mean that anything is actually sent to the browser at that time. You need to flush the RESPONSE object (though I do not know if that does anything before RESPONSE.write() has been invoked). 2) It is invalid to mix non-header material in with the header. Just because some browsers handle it gracefully is not a good reason to do so. 3) Not all browsers will understand chunked data transfer. If you want to see how long you are waiting for a response, you can invoke your page by submitting a form, and using javascript, load a page that only says "Starting..." When Zope does send its response, it will overwrite that temporary page. I have used a similar method - although I always had the response come up in a second frame, and i am not sure if this will work if you only have a single frame. Another approach is to have your response open in another frame or in a popup window. Any of these variations will let you see the start and end of the response. Cheers, Tom P
Here is the dtml code I have been using:
<dtml-call "RESPONSE.setHeader('Transfer-Encoding', 'chunked')"> <dtml-call "RESPONSE.setHeader('Content-Type', 'text/plain')"> <dtml-call "RESPONSE.write('Starting')">
<dtml-call "wait(5)">
<dtml-call "RESPONSE.setHeader('Transfer-Encoding', 'chunked')"> <dtml-call "RESPONSE.setHeader('Content-Type', 'text/plain')"> <dtml-call "RESPONSE.write('\n\nDone')">
The 'wait' routine is a simple external method:
import time def wait(self, secs): time.sleep(secs) return
What I expected to see was the word 'Started' displayed in my browser, followed by a 5 second delay, and then see the word 'Done' displayed.
What I get is a 5 second delay and then both 'Started' and 'Done" appear at the same time.
Any ideas as to what I am doing wrong?
