Doesn't seem to work with ASA Anyconnect client-based VPN?

The GUI says I'm connected but just sits there with 'POST'

Note this isn't a clientless SSL VPN where you just have access to certain office functions via a web interface, the solution is a full SSL VPN via the downloadable Anyconnect client.

Not the ASA administrator but have worked with them before and would be keen to help debug if necessary...
