    multiple connection to squid proxy random bad gateway

      hi to all i'm new in this forum.


      i have this configuration

      2000 client ->urlfiltering7.3 ->squid proxy cache -> internet

      squid see only a Ip address from url filtering that made the request.

      randomly some client not show the page and after refresh of browser the page

      is visible.


      in squind.conf i haven't any restriction about maxconn or limit connection

      per ip.

      but from url filtering log i see a lot connection time out from squid like this

      Next hop proxy x.x.x.x has been marked as down for 1 seconds..


      the previus configuration with the same squid server and same configuration


      client -> squid-> internet ( squid see all ip request)

      and i'haven't the problem.


      there is some DDOS directive in squid that limit the number of connection

      with single IP ?

      or some directive that insert a delay like ddos protection for multiple

      connection with single ip?

      or some setting for allow many concurrent connection from same ip


      i appreciate some help

      best regards
