What I want:
I use a LOAD helper, which refreshes a page every second. But it would be
better to transfer this page only if it has changed. Anthony wrote on
http://stackoverflow.com/questions/14515313/how-to-modify-web2py-download-function-to-return-304-not-modified-in-case-the
how to change the header. I have added an ETag-field, but it does not seem
to work.
In order to test the idea I wrote:
def mytime():
jetzt=str(request.now)[:19]
mtime = "Mi, 06 Aug 2014 08:11:00 GMT"
response.headers['Last-Modified'] = mtime
response.headers['Pragma'] = 'cache'
response.headers['Cache-Control'] = 'private'
response.headers['ETag'] = "123"
return dict(jetzt=jetzt)
request.now gives the actual time, but if "Last-Modified" and "ETag" are
always the same I think I should see the same time on each call.
Ok, it does not work - what is wrong? Any ideas?
Regards, Martin
