When you send an HTTP request, most servers will respond with the content length. For instance, if you go to http://web-sniffer.net/, you can type in the file you want to view and you can see the header sent and received, and for the example you gave, you'll notice the HTTP Response Header includes a line Content-Length: 4054802 That should be the information you're looking for. -- http://mail.python.org/mailman/listinfo/python-list

Typically you would just do an HTTP HEAD request in order to get
information about the file without downloading it, but I tested the
given site and it does not seem to support the HEAD request. Instead I
used the GET request and read the headers in which contains information
regarding the file as well, but opted no to read the data to avoid
downloading it.
import httplib
connection = httplib.HTTPConnection(www.roche.com)
connection.request(GET, /rochea_z_sp.pdf)
response = connection.getresponse()
print response.status, response.reason
print File sie: %s % response.getheader('content-length')
Also you can do:
import urllib
response = urllib.urlopen(http://www.roche.com/rochea_z_sp.pdf;)
print response.info()
Hope this helps.
