Athena & browser 2-connection limit
by Harald Blåtand Dec. 17, 2008

Dec. 17, 2008

Hi there, Been thinking about this. It _would_ be cool if you could have more than one LivePage per browser session, like in popups, or even frames. What do you think: Is there any obvious & fundamental reason why the ReliableMessageDelivery stuff couldn't be modified, so that one instance of it could be shared between several PageWidgets?

Proxy Authentication with a Password Protected Site
by Robert Hancock Sept. 23, 2008

Sept. 23, 2008

from twisted.web import client from twisted.internet import reactor import base64 import sys def printPage(data): print data reactor.stop() def printError(failure): print >> sys.stderr, "Error:", failure.getErrorMessage() reactor.stop() if len(sys.argv) == 4: url = sys.argv[1] username = sys.argv[2] password = sys.argv[3] basicAuth = base64.encodestring('%s:%s' % (username, password)) authHeader = "Basic " + basicAuth.strip() client.getPage(url, headers={"Authorization": authHeader}).addCallback(printPage).addErrback(printError) reactor.run() else: print 'Usage: get_web_page.py <URL>' If I run this against a password protected HTTP(S) site from a host that has direct access to the Internet it works fine. I now have to move it behind a proxy that requires authentication. The Twisted documentation did not make it clear (to me) how to add proxy authentication and I cannot find an example on the Internet. I've tried adding an additional Proxy-Authentication header to the call, but that doesn't help Any ideas would be greatly appreciated.

HTTPPageDownloader closes 'file-like object', file-like object goes bye-bye
by s s Sept. 23, 2008

Sept. 23, 2008

Hi, This is my first post to this list. I've been using Twisted for a few (like three) days. My wife had a baby two days ago, no, really. I just got the other two kids to bed and thought I'd ask...sorry if this has been answered eleven-thousand times before but I did search the archives first. I'm writing a client app that needs to get the contents of a URL, usually just a web page. I'm trying to use client.py's downloadPage(url, file, contextFactory=None, *args, **kwargs): It claims to use a 'file' which, according to the docstring, can be a file or file-like object. It uses the HTTPDownloader class to perform the actual download. In the pageEnd(): method of HTTPDownloader, the 'file' is closed. Unfortunately, for 'file-like' objects, like StringIOs, this trashes the 'file'; not so useful since I need to work with the result. I realize I can subclass and override and such but it seems odd that a function that is documented to use a file-like object uses a class that will destroy something that's not a 'file.' I'm sure I'm missing something...or maybe nobody uses this 'cause there's something way better that I haven't discovered yet. Clues? Thanks, S, AKA: Steve Steiner

how do I handle file upload (on the server) using twisted.web
by Chenglim Ear Sept. 19, 2008

Sept. 19, 2008

I have an http server set up using twistd. I searched for some answers on the web and saw something regarding getting the uploaded file from request.content. I tried calling request.content.read and did not get the file uploaded. I was able to see something if I call request.content.seek(0) first, but the information is just the name of the input field and the filename of the file that I uploaded. Am I forgetting to do something to ensure that the file is actually transferred? If somebody can point me to information about what's available from the "request" object and how to use it, especially to extract the uploaded file, that would really be helpful. Chenglim.

.js File caching behavior on different browsers
by Werner Thie Sept. 16, 2008

Sept. 16, 2008

Hi all Tried to send this to divmod-dev(a)divmod.org, but post didn't show up after 12hours. Might be an insanly stupid question but, is there a simple way to force the reload of JScript code for nevow LivePages via a server issued directive? I ask because Firefox seems to cling to the JScript files until the user forces it to forget them with 'Clear Private Data', which leads to ugly mismatches between server and client side code. Thxs, Werner
