Another way to do it, based on http://docs.python.org/2/library/basehttpserver.html#more-examples, is: instead of serve_forever(), keep serving as long as a condition is met, with the server checking the condition before and after each request. For example:
import CGIHTTPServer
import BaseHTTPServer
KEEP_RUNNING = True
def keep_running():
return KEEP_RUNNING
class Handler(CGIHTTPServer.CGIHTTPRequestHandler):
cgi_directories = ["/cgi-bin"]
httpd = BaseHTTPServer.HTTPServer(("", 8000), Handler)
while keep_running():
httpd.handle_request()
