Hi guys,

Here is the action I request:

def index  
@producteurs=Producteur.find(:all)  
last=Producteur.maximum(“updated\_at”).utc  
if stale?(:last\_modified=\>last)  
ip=request.remote\_ip  
@centre=centrage(ip)  
respond\_to do |format|  
format.html  
end  
end  
end

for the first request I get a “200 ok” response in firefox  
for the second request I get a “304 Not Modified” response in firefox,  
GREAT  
but for the third request I get a “200 ok” response. ☹ Nothing  
has change in the models.

Any idea why the third request is not a 304?  
thanks jef.
