Server - NetWare 6.5 sp8, BM 3.8 (latest patch, I believe)

We are blocking access to all sites with the exception of those explicitly authorized and thus we have setup a series of rules to permit access and block everything else. One of the sites permitted is Pandora.com. However, in placing http:\\*.pandora.com\* in the rule for allowing HTTP access via the proxy, it does not work. The site starts to load but then stops. Apparently, there are other URLs that need to be included. When accessing Pandora.com via the proxy without any access restrictions, Pandora works fine so there is no inherent problem with using the BM proxy server. Any help would be appreciated. Thanks.
