Is there a way to support SOCKS type proxy?
A. AnyConnect is not supported with SOCKS type proxy. SOCKS is not a HTTPS proxy, so Cisco does not support SOCKS proxies. AnyConnect will work in SSL mode via “HTTPS” proxies (specifically HTTPS 1.1). Additionally, authenticating proxies that use Basic or NTLM for authorization can also be used. You must enable use https 1.1 for proxies in the advanced IE settings.
