simple squid proxy with http authorization

Squid (caching) proxy has been used on the Internet for ages. The first release of Squid was back in the mid-90s!
Here is how you may use Squid as a proxy HTTP server with user and password authorization (it is easy to enable the caching, but we do not include such configuration). Our system is CentOS 7, but the configuration part is platform-independent, so just install it in your Linux distribution and use our configuration lines.

STEP 1) Install Squid

The instalation under CentOS 7

yum install squid

STEP 2) Squid configuration to use it as web caching proxy.

The configuration file is located in “/etc/squid/squid.conf” and you should add at the begging the following lines:

visible_hostname srvname
auth_param basic program /usr/lib64/squid/basic_ncsa_auth /etc/squid/pass.squid
acl ncsa_users proxy_auth REQUIRED
http_access allow ncsa_users
auth_param basic program /usr/lib64/squid/basic_ncsa_auth /etc/squid/pass.squid
