BCB6 patched.

I have had one developer tell me that my application that calls a 
web-service should "just work" from behind a proxy server.  Is this true?

I am suspicous of this because I have had one client tell me that my "check 
for updates" functionality fails because they are behind an *authenticating* 
proxy server.  As far as that goes I have modified that check for updates 
code to be like this:

if (globalOptions.UseProxy)
{
    IdHTTP1->Request->ProxyServer = globalOptions.ProxyName;
    IdHTTP1->Request->ProxyPort = globalOptions.ProxyPort;

    if (globalOptions.UseProxyAuth)
    {
        IdHTTP1->Request->ProxyUsername = globalOptions.ProxyUserName;
        IdHTTP1->Request->ProxyPassword = globalOptions.ProxyPassword;
    }
}
AnsiString response = IdHTTP1->Get(fullURL);

I believe that will work - but not sure because I havent set up the 
necessary proxy server to test.

Now, as far as the web-service goes, I could do something similar - but the 
import BCB creates uses THTTPRIO to invoke the service and it does not have 
such proxy server details.

What do you think I should do?

TIA.
M.

Only if the application's code takes the proxy into account.  Otherwise no.

You need to use the ProxyParams property instead, ie:

    IdHTTP1->ProxyParams->Clear;

    if (globalOptions.UseProxy)
    {
        IdHTTP1->ProxyParams->ProxyServer = globalOptions.ProxyName;
        IdHTTP1->ProxyParams->ProxyPort = globalOptions.ProxyPort;

        if (globalOptions.UseProxyAuth)
        {
            IdHTTP1->ProxyParams->ProxyUsername =
globalOptions.ProxyUserName;
            IdHTTP1->ProxyParams->ProxyPassword =
globalOptions.ProxyPassword;
        }
    }

TIdHTTP in my version (BCB6) does not contain a "ProxyParams" property.

Is there an update I should have?

BCB 6 ships with Indy 8, which is no longer supported.  You need to upgrade
to Indy 9 or 10.
