I am not sure whether this is ruby question or networking question..
but this group is so resourceful that I came over for some help onto
it.

We have developed a ROR application that pulls data from a Network
element and generates Hourly dashboard for the element.

There are 25 such elements spread ac the country.

Apache/Mongrel combination is used in each of these dashboard
generating machines.

Upto this it is fine...

Now... the requirement is users who are suppose to access the
application should be capable of reaching any of these machines for
visibility of DASHBOARD.

Problem is... the application server resides in a domain ... whereas
users need to access it from the same domain or another domain which
the firewall policy of the org does not permit.

We have at our disposal one server (WINDOWS IIS) which can talk to
both of these domains.

What we need is ... some kind of code  sitting on this server that can
proxy/forward etc to the corresponding dashboard generating ROR
application.

I hope i have been able to state the problem clearly.

Any help/pointer/tutrial on how to acheive this would be great.

Cheers
