(advance warning: this may be a more developer-focused issue.  If so,
pointers to the proper newsgroup would be appreciated...)

Hi all:

Have made an interesting discovery during the course of a current
development project...when attempting to download a file from a site not in
the users's trusted zone, the popup asking for permission to download the
file apparently re-submits the original request a second time rather than
passing the response from the original request through to the browser.  We
have verified that this only happens when the site is not listed as trusted.

This is stressing our team's application, as it is dynamically assembling
content on a request basis...any of our IE users are requiring our back end
to generate the same content twice.

We are advising our clients to add our site to their trusted zone to work
around this.  The majority of our clients, however, work in locked down
environments and don't have the luxury of doing this.  My question to the
group:  any server-side-driven solution we can use to mitigate this
double-dipping, as it were?

Thanks in advance,

-E-
