[squid-users] Why squid -> VW -> squid?

Hello,

Trend Micro recommends that Squid and their Virus Wall software
be configured like this,

Trend Micro says,
> The exact network configuration for InterScan VirusWall 3.6 for
> Unix to be able to use the Squid ACL system should be as
> follows:

> Client ---> Proxy#1 (Squid) ---> InterScan VirusWall ---> Proxy#2 ---> Internet

> The addition of Proxy#2 is necessary because VirusWall will use
> it to connect to the Internet. This configuration is valid
> whether the Internet gateway is protected by a firewall or not.

I've asked them several times *why* the second squid would be
necessary - I don't understand why one would need Proxy#2 - why
not send the request directly to the content server?

Thanks,
