Re: SSL VPNs and security

That depends on whether the solution tries to solve single-sign-on
problems as well.  If the vendor is trying to handle SSO in such an
environment, then they are probably using domain cookies.  The
problems are exactly the same as the ones Michal listed, plus some
additional ones specific to domain cookies.

Right, that does make it difficult.  There's probably work arounds, but
they may be browser-specific.  Wildcard cookies, cookies set to other
origins, or somehow setting document.domain back to the base domain
after the initial page load might help, but some would probably present
the same problem.

The web was never designed for complex application development.  At
least, web standards aren't.  Use a real VPN. 

cheers,
tim
