Maybe you can contain everything you need to do in a single .py file and run it. Or maybe it would be beneficial to use separate modules or packages. These aren't really twisted-specific concerns. It's a matter of laying out your application so you can import the code you need, where you need it. If you have all of your Resources in a separate module or package, then you need to figure out how to import those and hook them up to the Site object. Extending the simple example from earlier, you might have a "run.py" in your app: ## myapp/run.py # from twisted.web import server from twisted.internet import reactor from myapp.views import MyResource site = server.Site(MyResource()) reactor.listenTCP(8080, site) reactor.run() This is highly simplified, but hopefully you can see it's just basic python. twisted.web.server.Site needs a Resource, so you have to figure out how to supply it.

But I still have my same question: Should I write a separate file containing all the resources and another file with the server? To deploy a content server on the RPi, do I need to wrap all the files within a .tac file?

Making a new factory for each *client* connection isn't unusual -- just for servers. 2. The API you probably want to use is twisted.web.client.Agent. 3. You could do something like this (I wrote no tests for this!) def timeURL(agent, url): return agent.get(url).addCallback(_responseReceived, time.time(), url) def _responseReceived(response, startTime, url): elapsed = time.time() - startTime print "Elapsed for {}: {}s".format(url, elapsed) # Note: response received gets called before the entire body is received ... or you could wrap that startTime and URL state in an object, of course :-) hope to help lvh _______________________________________________ Twisted-web mailing list Twisted-web&lt; at &gt;twistedmatrix.com http://twistedmatrix.com/cgi-bin/mailman/listinfo/twisted-web </pre> Laurens Van Houtven 2013-06-13T14:34:06 http://permalink.gmane.org/gmane.comp.python.twisted.web/5012 <pre>Hi there!

It doesn't magically use threads for Twisted work - Twisted is single-threaded, and does all it's work in one thread (except for adbapi and a few edge cases) The ThreadPool is for *your* code. It won't do anything unless you call deferToThreadPool or similar. transport.setTcpKeepAlive - see here: http://twistedmatrix.com/documents/current/api/twisted.internet.interfaces.ITCPTransport.html#setTcpKeepAlive </pre> Phil Mayers 2013-06-11T23:02:23 http://permalink.gmane.org/gmane.comp.python.twisted.web/5009 <pre>Folks, I am a little confused, and I haven't been able to find anything in the Twisted docs regarding this? pool = threadpool.ThreadPool () root = Resource () root.putChild ("resources", File( server_root + os.sep + "resources") ) root.putChild ("thumbnails", File( server_root + os.sep + "thumbnails") ) root.putChild ("templates", File( server_root + os.sep + "templates") ) root.putChild ("albums", Gallery() ) factory = Site ( root ) print "Listening on Port 8888..." reactor.listenTCP ( 8888, factory) reactor.run() I can't find how to add a ThreadPool to a standard reactor?

So I don't see what would stop you from inheriting this method if you subclass twisted.web.http.Request. You might get more helpful information if you explain what you actually want to achieve, though. See http://www.catb.org/esr/faqs/smart- questions.html and http:/sscce.org/ for some tips. Unfortunately I can't read the UI on that page, so I can't actually download it. A good example will fit inline in an email, though.

With 100 Continue support you might be able to work around that but then you need to be communicating with a server that supports that feature. Hopefully the currently-in-development tubes API &lt;https://twistedmatrix.com/trac/ticket/1956&gt; will make it easier to accommodate this requirement (and if not then perhaps the tubes API *should* make something like this easier.) -Jonathan </pre> Jonathan Jacobs 2013-04-07T19:23:03 http://permalink.gmane.org/gmane.comp.python.twisted.web/5001 <pre> On Apr 5, 2013, at 8:15 AM, Matt Behrens &lt;matt&lt; at &gt;zigg.com&gt; wrote: Great!
