To allow users to access the caches at specific times using Squid proxy server

Squid is a proxy caching server. An HTTP proxy server is a program that accepts requests from clients for URLs and fetches them for the client and displays the results to the client. A proxy is also used for caching commonly requested pages so that it may retrieved for the users for future uses. In this tutorial we will be briefed about the explanation on how to allow some users to use the cache at specific time duration using Squid proxy server on CentOS 6.7.

[root@server3 ~]# service squid status

Create a file named sites.txt and enter the websites name that had to be blocked. Save and exit the file.

[root@server3 ~]# vim /etc/squid/squid.conf
acl users src 192.168.7.206 192.168.7.216
acl access dstdomain "/etc/squid/sites.txt"
acl break time 06:17-06:20
http_access allow users access break
