I have a Python web client that uses urllib2. It is easy enough to
add my own HTTP headers to the outgoing requests. I just create a
dictionary of the headers I want to add, and pass it to the Request
initializer.
These custom headers are not all that gets sent. urllib2 attaches
headers also. Y

yes, that method only shows you all the headers added by urllib2.
there are other headers that are produced by httplib under the covers
that are added to the outgoing

those are exactly the headers I want to capture.
do you know how to get a hold of them from a request using urllib2.

now that I think of it, if it is only 3 headers, I can just override
them explicitly from urllib2 and then log that.
thanks a lot for looking into the httplib source!

I liked Tk a lot, but also moved to wx because of Tk's L&F. Tk is
great for simple tool interfaces. Great news.

os.fork is not cross platform. It is *nix only. Subprocess runs on
Windows also. The OP never specified his platform.

this is great news.. thanks for tracking 3.x so closely. I big

I think like this:
opener = urllib2.build_opener(urllib2.HTTPHandler(debuglevel=1))

I'm not sure exactly what you mean by "screen capture". But the
webbrowser module in the standard lib might be of some help. You can
use it to drive a web browser from Python.
to load a page in your browser, you can do something

+1 Matplotlib.
It's a very nice module with impressive graphing/charting/plotting
capabilities.

you aren't doing a read(), so technically you are just connecting to
the web server and sending the request but never reading the content
back from the socket. So your timing wouldn't be accurate.
try this instead:

I tested with Windows XP and Python 2.5.4. I don't have a 2.4 setup I
can easily test with.
you can try httplib rather than urllib2. httplib is slightly lower
level

true.. I didn't think of that. I was assuming the client machine
wasn't resource constrained. That would definitely lead to inaccurate
timings if that was the case.

Another vote Matplotlib. It has impressive graphing/plotting
capabilities and is used as a Python module/library.

"matplotlib is a python 2D plotting library which produces publication

yes, you can use "urllib2".
from the urllib2 docs:
"The default is to read the list of proxies from the environment
variables"
So if you have a proxy setup, it should detect it from your
environment vars. If you want to spec

you might want something like Expect.
