   This is because it uses dictionary, which may (and usually does) changes
the order of keys.

   Wow! what a foolish server :)

   I have a very little patch for urlencode that allows to pass lists, not
only dicts. My version is this:

# obj must be either dict or list of tuples [(k1, v1), (k2, v2), ...] or list of lists [[k1, v1], [k2, v2], ...]
def urlencode(obj):
     l = []
     if type(obj) == type({}):
         obj = obj.items()

     for k, v in obj:
         k = quote_plus(str(k))
         v = quote_plus(str(v))
         l.append(k + '=' + v)

     return string.join(l, '&')
