You'd have to base 64 encode and decode any binary data in HTTP.  There's
nothing in cpp-netlib which does this, but you can use:

https://svn.boost.org/trac/boost/browser/trunk/boost/archive/iterators/base64_from_binary.hpp

before copying your data to the message on the server and.

https://svn.boost.org/trac/boost/browser/trunk/boost/archive/iterators/binary_from_base64.hpp

for the client.

HTH,
