TCP SYN is handled by your TCP kernel. Squid does not become involved
until the full TCP handshake have finished.
TCP is processed by the TCP kernel. Squid deals with HTTP which runs
ontop of TCP.

This cannot be done in a proxy without also heavily modifying the TCP
kernel of your operating system.
See previous Squid-dev discussion on fully transparent proxying a couple
of weeks back for some related discussions.
