I have found that some of my users are listening to radio stations using internet, which has pumped up the internet bill significantly, and of course put a choke on my internet links. Does anyone know of a solution for blocking just the streaming media traffic from any web site, while still allowing the access to the website it self? Thanks, Ivan ######################################################## This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean. postmaster@xxxxxxxxxxxxxxx MailScanner at bandwidthco.com is for your absolute protection. ######################################################## ######################################################## This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean. postmaster@xxxxxxxxxxxxxxx MailScanner at bandwidthco.com is for your absolute protection. ########################################################
