squidguard not doing anything in redirecting the viralator part

[Yong Bong Fong]

Dear all,
 I have got a working squidguard trying to add viralator onto it. I am 
not sure why, seems like squidguard is not doing anything on the acl 
part for viralator. Below is my configuration for squidguard.conf:

#Provided by Jorge Flores" <[EMAIL PROTECTED]>
#squidGuard.conf --> /etc/squid/squidGuard.conf
logdir /var/log/squidguard
dbhome /var/db
#### Group of domains & urls with access permit
dest porn {                    
    domainlist blacklists/porn/domains              
    urllist    blacklists/porn/urls        
}                            

#### Group of file types to be scanned or forbidden to download
dest scan {
    expressionlist blacklists/scan/expressions
}
#### "file" is the name of control list
#### "files" a file in the  subforder proibidos under folder db
#(/etc/squid/squidGuard/db
#### Group of users to apply the polices
src users {
    ip 172.16.0.1 - 172.16.0.253
}
#### Apply rules based in the created control list above
acl {
users {
        pass !porn !scan all
        redirect http://www.suretecsystems.com/redirect/index.html
}default  {
        pass !scan all
        redirect http://172.16.0.105/cgi-bin/viralator.cgi?url=%u
}
}
    
When I change the acl for porn redirection from "users" -> "default" the 
porn redirection stop working. When I change it back to "users" porn 
redirection works. However I can never get the viralator redirection 
part working. Is there a problem with my configuration?

Hope anyone cna help me,
thanks in advance,
Regards
Yong
