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.
