Yes it can be possible with asa. The ASA 5520 does support 750 WebVPN connections, but the it only comes with a license for two concurrent users for evaluation. If you need more, you will need to contact your account team/reseller to get a license for additional users.
Are you talking client SSL or clientless SSL? If client less you must configure the ASA to permit browsing and then you enter the web address in the home page and it will retrieve the page from the ASA and paint it for you.
I actually have the same question. I'm using the AnyConnect client to connect to an ASA 5510 via SSL VPN. I can view any internal resources just fine, but whenever I try to access an Internet website I can't get through. I would really prefer to tunnel all traffic when connected for security reasons.
