Re: [Cppcms-users] per request data storage?

[陈抒 <csf...@gm...>]

Not sure the different locations mean what? Different web URLs?
If you want to save something in web app, in my way, I usually create a
singleton object called my_app, you could use any singleton technology to
create it. And save the variables that you want to cache and share  as the
my_app object's member variable.
For multi-thread protection, use boost::mutex to protect them.
