Thanks Joerg and Marcel,
you open new avenues of investigation for me.

I've just been researching the base64 solution, and I fail to see where to 
employ it and how it would solve the problem.

First, the HTTP protocol does not use base64 encoding. It supports binary 
streams natively (how else would pictures and what not be transferred?). 
As far as I am aware, Base64 was/is mostly used for mail transport.

Secondly, unless I missed it, the PDF protocol does not support base64 encoded 
PDF files. I cannot find any information about this.

What am I trying to do?
Create within my cppcms application a PDF document on the fly (dynamically), 
and return a proper .pdf file to the user via cppcms and the HTTP protocol.

As far as I am aware, the problem is either within my cppcms application or 
within cppcms itself. 
My experience is limited, and I may be missing something, but I fail to see at 
what stage to use Base64 strings and how it would help.

I'm still looking and testing...

Cheers,

augustin.
