Hello all, some of my users complain that a page (www.bestjobs.ro) with cookies and some other stuff hangs sometimes, returns "Connection reset by peer" and so on. Some problems can be resolved by reloading the page, some can not. The pages that make problems are not the normal ones but after logging in and using some of the "more advanced features" of the web server regarding commenting to some of the information there. If the users access the web server without squid -- directly connected to the internet -- it all works. It seems to me that the problems have something to do with DNS; www.bestjobs.ro returns not one but 5 IPv4 addresses. With Windows XP and no proxy the browser always uses only one IP; squid -- I use version 3.0-STABLE 11 on RedHat AS 5 -- uses all 5 IPs in a round-robin fashion. The web servers do not serve static but dynamic pages and therefore I think the requests _should_ always go to the same IP address. But the load balancing probably makes the problems. I am fully aware that the problem is not the fault of squid but of the DNS loadbalancing of the web servers. Nevertheless I have to provide a solution... Is there a parameter within squid to change the behaviour of DNS load balancing when there is more than one IP in a DNS response? I do not want to disable load balancing but put a "on hold" parameter so that squid uses the same IP maybe a minute and then switches to the next IP and uses that for the next one minute and not a different IP for every request. Even better would be a source address affinity -- for one client all requests go to IP 1 of the pool, the next client is routed over squid to IP 2 and so on. Is there a solution to that?
Sure, try: http://www.squid-cache.org/Versions/v3/3.0/cfgman/balance_on_multiple_ip.html Regards Guido - ======================================================== Guido Serassio Acme Consulting S.r.l. - Microsoft Certified Partner Via Lucia Savarino, 1 10098 - Rivoli (TO) - ITALY Tel. : +39.011.9530135 Fax. : +39.011.9781115 Email: guido.serassio@xxxxxxxxxxxxxxxxx WWW: http://www.acmeconsulting.it/
