Not possible under ordinary circumstances.

To the best of my knowledge, it cannot be done by modifying Squid alone.
You would also need to hack some kernel source code.

The Vixie Web Gateway Interceptor (http://www.vix.com/vix/wgi.html)
could do this (apparently). I don't know if WGI exists as a product
any more. Maybe some other commercial products can.

I'd love to talk to anyone with the resources (especially money) to
make this work with Squid.
