Hi, First of all I want to thank you for your answers. I get the Squid.conf default file and i replace the other Squid.conf file. I just added cache_effective_user proxy-server because i'm administrating Squid with Webmin and everything works great. But i still have this problem with some web page like Google.com,youtbe,facebook.... I cheked the access.log file under /var/log/squid3 and i notice that some web page use non safe ports to connect (like 809,807..) Join to this post you will find my squid.config file what you recommend me to do???
