(non-HTML version.....sorry about that)
I use Twisted Web on an embedded Linux device to provide browser-based
configuration & control. The browser displays a bar graph of a parameter
that is quickly changing on the embedded device (peak audio level). In
order to provide a reasonable feedback to the user, the browser connects to
the Twisted Web CGI server once a second via XMLHTTPRequest to obtain an
updated bar graph level, then Twisted Web dutifully closes the connection.
Is there a way to achieve the same thing without opening & closing a
connection each time?
My code:
# ----- Set up the web/CGI server to handle browser-based control -----
from twisted.web import server, static, twcgi
root = static.File("/myResourceDir")
root.putChild("cgi-bin", twcgi.CGIDirectory("/myResourceDir/cgi-bin"))
reactor.listenTCP(8000, server.Site(root))
Thank you.
