Re: [cpp-netlib-devel] cpp-netlib async server request - bad cast exception thrown

Hi Max,

Sorry for the late response this time, I've been asleep for a bit and
taking a break earlier today.

Please see thoughts below.

Can you please send the exact request that the browser sends over the
line? Can you please use something like FireBug to catch the raw
request (with method, headers, and body) that it sends to the server?

This is it? Unfortunately you'd need to write out headers and data to
the connection too for anything to actually be sent through the
connection.

Please check the test in libs/network/test/http_async_server.cpp to
see what an asynchronous handler should look like.
