That's what I'm already doing.
From the code I posted at the beginning:

std::ostringstream cppcms_buf(std::ios::binary); 
...
// cppcms::http::response:
app()->response().out() << cppcms_buf.str();

Do your pdf contain only plain text, or do they contain graphics?

Can you post a simple hello_world.pdf code, especially the part where the 
generated PDF is sent back via the cppcms output stream:
cppcms::http::response().out()
?

I hesitated between using libharu and PoDoFo.
Neither library is well documented. 
I just started with libharu but it's not too late to switch to another 
library.
Are you happy with PoDoFo?

Thank you, Joerg.
