hello, i need help or suggestion. my ISP is using multiple sibling/parent proxy for my internet connection. As I trap the header for each reply http i found similar headers like this : X-Cache: MISS from cache2.of-my-isp-proxy.com X-Cache-Lookup: MISS from cache2.of-my-isp-proxy.com:8181 X-Cache: MISS from another-proxy.of-my-isp-proxy.com and when i count byte used for those headers it could reach up to 185 byte per single reply of http request. Considering that my organisation use alot of pc's (98 stations) with single internet connection shared up to 1 mbps, i found that those headers would consume our downstream bandwidth quite hugh. i assumed that each station would request 4 pararel connections per second (as IE browser do) to the gateway. i then multiply this to 49 (50% of all stations) and then multiply to 185 byte (max byte header x-cache consumed) equals to 36250 Bytes per second. Then i multiply it with 8 (converting from bytes to bit) equals to 290080 bits per second alias 290kbps. For short : 4(req)*49(units)*185(byte)*8 = 290k / second i then write email to the ISP, complaining those headers consume our bandwidth so much. i ask them to eliminate those headers on every reply as i found fact that those headers mean nothing for us but junk headers. It consume our bandwidth up to 290kbps loss for nothing. I ask ISP to deny x-cache headers for all of our IP Addresses so those junk headers won't appears again in every single http replies from their servers. And its been 8 days since i ask them to remove those headers but until now i still see it, i guess they can't do it (for some reasons) or just don't know how to do that. i told them to add these below configuration to their squid.conf : headers X-Cache deny <our IP ACL> headers X-Cache-Lookup deny <our IP ACL) to eliminate those headers. but i'm not sure well coz i don't know how they manage their squid (linux) servers configuration. What i know is that conf works well on my SquidNT. so, how to eliminate those headers precisely under squid.conf? we need replies soon, thank you regards, Pudjo @Galerinet Cybercafe Indonesia __________________________________________________ Do You Yahoo!?
