Is there any free HTTP SSL VPN clients around, one that can act as an alternative to Cisco's own HTTP SSL VPN client (called AnyConnect)?

The Cisco AnyConnect client has acknowledged problems, with no forthcoming solutions. Which is why I'm hoping for an alternative.

Note: I'm only talking about the HTTP SSL VPN Client, not the HTTP SSL VPN Server. (If it were up to me they wouldn't be using Cisco at all, but it's not up to me.)

Note: OpenVPN is a client that talks to their servers once you sign up for their service. It's not a generic VPN client.

Note: ShrewSoft VPN is a client that uses IPsec and pre-shared keys, and was a good replacement for Cisco's old client - but not the new AnyConnect SSL VPN client.

Note: Windows 7's VPN client fails to negotiate when presented with an SSL VPN connection.

Note: I am looking for Windows clients only.

Well, in case anybody wonders: There's really no such thing as a "universal VPN client". This is especially true for proprietary VPN servers/extensions. –  Daniel B Feb 27 '14 at 9:14
Your note about OpenVPN is incorrect. OpenVPN is a generic VPN solution, which you can install on your own server and use OpenVPN clients to connect to it. See openvpn.net/index.php/open-source.html –  Tero Kilkanen Feb 27 '14 at 10:01

While there isn't a port "yet", the authors of OpenConnect seem to think it would be straightforward.

There is discussion of a port here.

Perhaps it would be worth investing the time to get it working given Cisco's response.

The Windows port of OpenConnect is now working, and there's even a GUI tool for it. See https://github.com/openconnect/openconnect-gui/wiki

Shimo (Mac only) seems to support Cisco AnyConnect among the others
