Hi Douglas,
I think you are looking for the 'EndResponse' exception. From
WebKit/Page.py:
def endResponse(self):
"""
If this is called during sleep() or awake() then the rest of awake(),
response(), and sleep() are skipped and the accumulated response is sent
immediately with no further processing. If this is called during respond()
then the rest of respond() is skipped but sleep() is called, then the
accumulated response is sent.
"""
So if your code is in a servlet or PSP subclassed from page, just call
self.endResponse(). If you are in deeper code (i.e. code called from the
PSP or servlet), do:
from WebKit.Application import EndResponse
raise EndResponse
peace,
Jason
