Squid limit web connections using maxconn acl

FREQUENTLY ASKED QUESTIONS (Squid proxy)
Q: How to limit number of symultaneous web connections in squid proxy?

Use "maxconn" ACL to limit the total number of symultaneous browser connections from a proxy client. If the maxconn access list configured to 5, the client can only access 5 simultaneous browser windows at a time.

Edit the squid proxy configuration file and create a maxconn acl
[root@server ~]# vi /etc/squid/squid.conf

acl accounts src 192.168.10.66/32                     #create a user acl to apply maxconn

acl limit5conn maxconn 5                                  # create maxconn acl

http_access deny accounts limit5conn                #apply maxconn acl to user acl

#Now save the squid.conf configuration file

Reload or restart squid

[root@server ~]# service squid reload
                  OR

[root@server ~]# service squid restart
