I don't think so; Have a look at this paper, on this very topic. It is
only the first step to take the idea to a fully functioning tool for
building web apps, but it is promising.

The basic idea is to use CPS plus a few other program transformations
to enable the web script to marshall the continuation into a hidden
field and send it across with the web page. Then, when the answer comes
back, you turn the data in the hidden field back into a continuation
and throw to it.
