[Zope] csv import continued

[David Siedband]

How could I adapt this code to get a CSV file from a remote URI instead 
of the request?

> Now i have an iterable file for the csv module in this code:
>
> def students(self,REQUEST):
>   import csv
>   f=REQUEST.form["students.csv"]
>   from cStringIO import StringIO
>   filebody=StringIO(f.read())
>   reader = csv.DictReader(filebody,("firsname","surname",
> "year","form","gender"))
>   for row in reader:
>    self.writestudents(row)

TIA,
