[Zope] Implementing a distributing mirror

[Luciano Caroti]

Hi,
I would like to implement a system to distribute PDF document. I would like
to use ZOPE on 5 server distributed in Europe. I would like to build a
system that send an email to a paying user where I put an URL. I would like
that in URL I send temporary authentication information to allow access to a
virtual directory where I put only documents or images files that user
purchased. Have you any hints on how implement this architecture?
Thank you in advance,
Luciano Caroti.
