[Zope] checking existance of an url?

[Michael Long]

According to the zope book 2.6 you can also check for the existence of
an object with the following python script, where "updateInfo" is the
object you are looking for:

updateInfo = getattr(context, "updateInfo", None)
if updateInfo is not None:
    updateInfo(color="brown", pattern="spotted")
else:
    # complain about missing script

This sounds like path would have to be a relative path and not a full
URL. What I have is the full URL like http://...

absolute path. But I would have to convert that to a relative path
right? Actually I was trying to get around converting the absolute path
to a relative path, but that doesn't seem possible.
