[plt-scheme] Restart Web-server

Hi Jasper -

I think you mean auto/event-driven browser refresh rather than restart the
web server.

There is something called the World framework in PLT that appears to handle
such needs - IIRC it works with Flash, but I never used it and don't know
how it works - others would have to chime in.

To do this on your own you can use either use the meta refresh technique, or
you can use some sort of ajax/comet to have the server notify the client to
refresh the pages.

http://en.wikipedia.org/wiki/Meta_refresh - although this is considered
obsolete by standards it is supported by all major browsers.  The meta
refresh happens with or without events occuring on the server-side.

http://en.wikipedia.org/wiki/Comet_%28programming%29 - this occurs only when
an event happened, but there is a lot more work involved.

You can also do this with Flash/Flex, which has its own dev model.
