urllib: geturl with max filesize?

[Alex]

I don't know about other security issues.  It may depend on what you
plan to do with the content the user points you at.  But you can limit
the download size fairly easily:

import urllib
f = urllib.urlopen(url)

data = []
while len(data) < 1024:
    block = f.read(1024)
    if block == '': break
    data.append(block)

f.close()
write(''.join(data))

...will restrict the download to 1M, I guess.
