It'd have been good to tell us that this was on Python 2.7

Is MyWebServer class intended to have exactly one instance?  If so, you 
could save the instance as a class attribute, and trivially access it 
from outside the class.

If it might have more than one instance, then we'd need to know more 
about the class BaseHTTPServer.HTTPServer,  From a quick glance at the 
docs, it looks like you get an attribute called server.  So inside the 
do_GET() method, you should be able to access   self.server.foo   and 
self.server.bar

See http://docs.python.org/2/library/basehttpserver.html
