What do you mean by that? What are you using 400 ports for?<br>

What authentication method / protocol do you want to use?<br>
<br>

<br>
I think the best starting point is to ask what sort of authentication you want <br>
to perform (ie: what is the authoritative system which holds the information <br>
about who can authenticate and who cannot), then you can decide on the best <br>
software to use to do that in front of Squid.<br>

Under UK law, no VAT is charged on biscuits and cakes - they are "zero rated". <br>
Chocolate covered biscuits, however, are classed as "luxury items" and are <br>
subject to VAT. McVitie's classed its Jaffa Cakes as cakes, but in 1991 this <br>
was challenged by Her Majesty's Customs and Excise in court.<br>
<br>
The question which had to be answered was what criteria should be used to <br>
class something as a cake or a biscuit. McVitie's defended the classification <br>
of Jaffa Cakes as a cake by arguing that cakes go hard when stale, whereas <br>
biscuits go soft. It was demonstrated that Jaffa Cakes become hard when stale <br>
and McVitie's won the case.<br>
