Thaks Thor and Andreas,
The problem is sure from cache, if desactive cache, all its Ok.
Now We try to put the meta tag,
<META Http-Equiv="Cache-Control" Content="no-cache"
/>
<META Http-Equiv="Pragma" Content="no-cache" />
<META Http-Equiv="Expires" Content="0" />
only if there is a user in cocoon enviroment session. With this we sure that
the page specialized are not caching.
But Maybe a register user recived a cache page without his correct user
cookie. Maybe we need that when a register user is detected, cache not work
for his request. But we not idea how to do that.
In other hand, we detected that the perfermance without cache is good too.
Temporary this is our solution.
Any idea to solve that problem.
TIA.
