Not in squid, at least not without first adding the feature.

Because the user have once installed a "download accelerator".. most
these change the registry settings to pretty much unlimited concurrent
connections from the default 2..

Yes.

Regarding source I think a good starting point is to look at the maxconn
acl. The big part is coming up with a method for detecting these
concurrent requests correctly. Discussions on this is best done on the
squid-dev list.
