SSLVPN cisco anyconnect client images
On an ASA when you go to Network client access < anyconnect client settings < add multiple image package (windows, mac, linux) < select a regular expression to match user-agent
How does the client computer know which image to tell the ASA to give it? So if a client computer is Windows, and it connects to the ASA for sslvpn, how does it tell the ASA it wants the windows any connect client package?

I'm not certain exactly how it knows, but I can verify it does. I believe during the connection process there is information about the client's OS that is passed and the gateway recognizes that and passes the appropriate client.

it says that you are mozilla/4.0 compatible. i am on xp with IE 7 and get Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; .NET4.0C; .NET4.0E; .NET CLR 2.0.50727; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729; MS-RTC LM 8)
the key for the regex with the anyconnect client is to use a lowest common denominator. like 'win' or 'mac', that is your real differentiator. also it goes top down so set up your most common client first.
