Varnish problem with creating new topic

[VecchiaSignora]

Hello everyone

 

we have varnish cache installed on our forum ( IP.Board 3.2.3), but with it there is a problem that we can't solve. After starting a new topic, forum have difficulties to redirect to the new topic created; indeed often it shows a blank page, so the user think that the topic was not created, turn back and press "send" again. Then we have 10-15 identical topics.
Can you help us to solve this problem?

Thanks everyone

 

Bye

Have you already tried Varnish with IPS 4?
