It is in Doxygen API:

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


Quoting:

    All changes in session should be done before headers are written
   to the output (before requesting an output stream from http::response object)

Also It seems that it should be more "highlighted" there.


Because it is quite FAQ there.
