I haven't but I'm sending my own requests and the only change I had to make to basic commands was to send via https instead of http. That requires certificate handling which is somewhat of a headache because those certs aren't invalid, but that's the main problem.

So I'd look into https post from an asp page and if you have that down, the rest will fall into place (you can re-use the code you're using for axl requests on ccm 4.x)
