[squid-users] Chaining url_rewrite_programs

We are using squid 2.6 and Websense as a url_rewrite_program and would like
to return a 404 to clients who ask for a particular file (
http://www.example.com/sametime/stlinks/DebugLevel.class). We have explored
chaining using zapchain but do not want to use adzap.
http://adzapper.sourceforge.net/scripts/zapchain

Can we chain using a combination of the zapchain script and the
custom.plexample from this link
http://www.powershelladmin.com/wiki/Linux_squid_proxy_url_rewriting_or_redirection
by
specifying this in the squid.conf?

url_rewrite_program /opt/zapchain/zapchain /opt/custom/custom.pl
 /opt/websense/websense
or
url_rewrite_program (/opt/zapchain/zapchain /opt/custom/custom.pl
 /opt/websense/websense)

Can anyone recommend another approach?
