One of the drawbacks of working at a company like 3Sharp is that sometimes we get so busy doing everything we do that I don't have enough time during the day to check out all of the new technology I want to. If we get especially crunched, I have time to learn about those things I need to know to meet the next deadline or produce the next deliverable...and I don't always feel like going home and playing with new bits there. (In fact, I rarely feel like it these days; when I'm on the computer at home, I'm blogging or writing.)
As a result, I've just not had the time to play with the beta or release candiate builds of ISA Server 2006. I may have to make some time for it, though, after reading Keith Combs' post about the HTTP over HTTP (his tongue-in-cheek name) feature of ISA Server 2006. The central concept is that instead of publishing a bunch of internal web resources directly to the Internet (even if they're protected by current ISA Server 2004 features, like IP-based access control, and ISA server pre-authentication), you require the user to log into the ISA Server (much like Outlook Web Access). Once they're in, they then have a list of the internal resources they can connect to.
Cool stuff...I'll be reading up on it.
