Squid is the wrong tool to be using here. You want to look at hacking
and attack tools - that is what you will be doing, and why it is illegal
in most cases.

Squid is only opening outbound socket, marking it with
setsockopt(IP_TRANSPARENT), then using bind() to set the outgoing IP.
Everything else is limited by normal TCP/IP and routing operations
within the network.

Note that Squid specifying the outgoing IP on any particular request is
a non-standard use of HTTP. Normal HTTP combines the client requests
into persistent connections. Causing a few long-lived TCP connections to
servers with a large number of pipelined transactions on each.
 For testing server capacity against TPROXY input it is suficient to
make the server listen on localhost interface and setup a tool like
Polygraph to use 127.0.*.* IPs for opening connections (or the fc00::*
range in IPv6).
