Hi,

Is Page.Cache global and shared between all session? What would be the best 
way to cache an object and share it btween all sessions?
I like to avoid Application object because it doesn't have Cache's 
flexibilities.

Thank you,
Max

Yes,

 Cache should be shared around sessions (not sure in a farm of servers).

  If you want you can make a dummy test:
     -  Add a Page cache of 30 minutes that read a value from a table in 
database
     -  Open an IE an Access the page (it should be cached).
     - Modify that value from the DB
    - Open another IE sessions and you will get the page without the labe 
updated from the DB.

Hi Max,

Yes, you Page.Cache is shared among all the sessions, actually Page.Cache 
is just HttpContext.Cache which is a global storage available within the 
entire ASP.NET application scope(AppDomain). And it is a good place to 
store some global data since it also provide some cachepolicy to make cache 
item expired(such as File based, Database based  or timespan based ....)

http://www.codeproject.com/aspnet/exploresessionandcache.asp

Also, other means for share objects within application scope include:

** store object/data in database

** use a public class's static member variables to hold objects

static member variable is useful for simple data caching scenario and you 
need to take care of the concurrent accessing and update of the data in 
shared static members.
