How to configure Htaccess authentication in Squid proxy server

Open squid configuration fine c:/squid/etc/squid.conf and add/modify the following.

Uncomment the below line.

auth_param basic program c:/squid/libexec/ncsa_auth.exe c:/squid/etc/passwd

The following needs to be in that order and I placed it right after the line 'acl CONNECT method CONNECT'.

acl ncsa_users proxy_auth REQUIRED

http_access allow ncsa_users

http_access deny all

Then add the htaccess user details to the file c:/squid/etc/passwd

Finally restart the squid service.
