Hi, We have been using Squid for many years now and recently we upgraded from 2.7 to 3.1 version. Since upgrading we started getting intermittent Access Denied messages for sites that we can access normally. For example, if we access www.google.com we get the site straightaway at times and on other times we get Access Denied message. Then, if we keep refreshing the page, the site comes up. We had our ISP connection checked by their support staff who visited our premises and got a Windows laptop connect directly without the proxy and everything was working excellently. With Squid 2.7 everything worked as a charm. So I am wondering what must be wrong. Any help would be greatly appreciated. Thanks in advance. Regards, Nitin
