Symbol Server without Virtual Root Cache

Hi (this started at http://social.msdn.microsoft.com/Forums/en-US/vssetup/thread/ff190818-2fe9-4ca6-a146-59ad3427b851 and i was advised to post here)

I am after help on setting up a http: symbol server for visual studio 2010 use.
Note i mean http://server:80 type of approach

NOT the UNC srv:<UNC path>

Due to Domain trust issues with the remote location (where we would like to run this), a UNC path can't be used, but the http: approach should work within our intranet.

We can NAT the addresses to get to the service and turn off security at the remote end (i.e. this will not be available via the internet, only the intranet)

NB: I am not talking a about a Symbol Proxy Server (with its own cache)

e.g. want

<us - our cache>  <==== http:80====> <them - say symstore on same machine A> <-- refs -> <machine B>

The symbols at the remote location have pointers to the the dll / pdbs which live on another server.
So at Machine A we have 500Meg of symbols with references to the actual files on Machine B which has Terrabytes of disk used.

What we DONT want is for the system to "cache" symbols on their side, i.e. crazy to have terrabytes to be duplicated when the server has direct access to the files...

On our side we would cache, to ensure only one download occurred to the remote location.
At the remote location NO caching to occur. Just fetch the files through their UNC paths.

e.g. http://msdn.microsoft.com/en-us/library/windows/hardware/ff558846%28v=vs.85%29.aspx without caching at the SymProxy.
i.e. no virtual root of the Web site file copy

>> I am after this technology ?

Thanks in advance
