I have a system which is accepting Base 64 encoded data from an

I am having an issue (Using Zope 2.7.6, Python 2.3.5) where the +
and / characters in the incoming data are being replaced with
spaces. Unfortunately, since both + and / are being replaced with
the same character, it is not simply a matter of doing a find and
replace on the string to restore these characters.
This system did work fine for a long while. I upgraded the
machine's Python from 2.3.5 to 2.4.1 a couple of months ago and
have now reverted back to 2.3.5.
Has anyone encountered a similar problem before and how can I work
around/through it?
Just base64-encoding and then attempting to pass that in a URL is not
safe. The right approach would be to base64-encode and then urlencode
before adding it into the URL.
