[Web4lib] Alternatives To EZProxy?

[federica zanardini]

Hi all,
in University of Milano we are using a squid-cache server to provide 
the off-campus access to Digital Library since 2001.
Squid is an open-source project, it's a very reliable and versatile 
software: we serve about 1500 users and use them also to manage the 
pubblic access computers in our libraries. The major concern is that 
is necessary to use a port different from 80, so users behind 
firewalls have problems to connect .  To solve this problem last year 
we installed also an ezproxy that works on the port 80 as a normal webserver.

If you plan to use squid-cache for off-campus access, keep in mind 
that is also necessary:
a) create a PAC (proxy autoconfiguration file 
http://en.wikipedia.org/wiki/Proxy_auto-config)  that should be 
located in a public accessible URL and should be loaded by the users 
browser (is used to select the domains/URLs to be proxied)
We have a very high number of domains/URLs to manage so we have 
automatized the PAC creation using a database and some jave servlet. 
This system is used also to create and update the Ezproxy configuration file.
b)  connect to an authentication/authorization system.
We use a central Radius-server used also by the institutional 
mailserver. The interface Squid-Radius is a perl script that use some 
modules distributed by CPAN.
