Re: [cpp-netlib-devel] New http::client code errors

[Dean M. B. <mik...@gm...>]

Hi Guys,

I've just checked in revision 48 which fixes the Python CGI script
that returns incomplete headers. I had to make it print the http
status line (which I'm not sure is required) and add the correct line
endings to the printed header: instead of just '\n', I made it print
"\r\n\r\n" in the end to signify that it was the last header responded
to.

Divye, please make sure that this is the correct way to do CGI scripts
in Python -- I really have no idea how to do that, and I only hacked
the script to make it not fail in just the CGI case. I haven't tried
this in Windows yet, but I'm thinking it should be do-able.

Another thing: maybe we should put the startup/shutdown of the server
in a global fixture in the test suite for localhost_test? Has anybody
done this with Boost.Test before? That way when we start the server,
we should be able to stop it as well at the end of the whole test.

HTH

PS. I will only now be doing the refactoring to support HEAD requests.
I'm pretty sure I'll be refactoring the client implementation to make
it "cleaner" and make the actual 'get' body implementation shorter.
