I use videocache to cache Youtube savings me thousands of dollars every month in bandwidth. Occasionally I am getting: "ALTERNATE_URL_OPEN_ERR YOUTUBE HTTP ERROR : 403 : An error occured while retrieving the alternate video id." and "DOWNLOAD_ERR YOUTUBE HTTP Error 403: Forbidden" Apparently the solution is to round-robin my local outbound IP address so that with each request the local outbound IP address changes. I am referring to is the "Forwarded-For" address that needs to change. I guess this makes Youtube think that my request is coming from another IP address then servicing it. Some guys on videocache even speak about having 10 different IPs. In order to get this working I added a virtual IP to the only interface on the box. Next I don't know what to do. I investigated 'tcp_outbound_address', 'round-robin', and 'balance_on_mutiple_ip' but none of these parameters appears to address my issue. 'tcp_outbound_address' sounded good but appears to only be applicable if you have different source networks. I don't want to round-robin based on the source network. I want to round-robin the local IP automatically with each outgoing request. Please assist. -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/Round-Robin-Local-Public-IP-tp2261691p2261691.html Sent from the Squid - Users mailing list archive at Nabble.com.
