#35 asynchronous applications automatically load session data

[CN Liou]

Asynchronous applications do not automatically load session data including cookies because doing so is costly according to documentation:

http://cppcms.com/cppcms_ref/latest/classcppcms_1_1session__interface.html#ae63e68dd2ec1d615f5a6a85bcee36605

Asynchronous applications not calling

bool cppcms::session_interface::load()

beforehand and try to access session data such as cookies will get unexpected results. Unfortunately, programmers like myself tend to repeatedly fall into this "trap".

request: If the auto loading is not too costly for asynchronous applications, please reconsider enabling automatic loading in favor of the benefit of programmers over system performance.
