Hello, I am using squid-3.1.11-1.el5 in a production server which acts as a gateway of our network. Every system is connected to the internet through the Squid proxy server. In my Squid configuration I am using "reply_body_max_size 15 MB officelan" to restrict download of large files. I am also using the following delay pool parameters to restrict Squid's overall bandwidth consumption. delay_pools 1 delay_class 1 1 delay_access 1 allow all delay_parameters 1 192000/192000 In my environment we have two ISP providers connected using two routers Link-1 and Link-2. Currently Squid uses Link-1 to connect to the internet. Currently if a download file size if more than 15 MB squid restricts the download as per the above configuration by my objective is to redirect requests through Link-2 if the download size is larger than 15 MB. While looking into the Squid mailing list archive I came across this post http://www.squid-cache.org/mail-archive/squid-users/200707/0678.html. I wen through the Squid documentation but I am not able to find how can a achieve it using Squid. Any help would be highly appreciated. Regards Supratik
