Close but not quite.
Squid can permit _unlimited_ speed for some initial amount of data, then
cap it lower. If your network is faster than 100MB Squid cannot limit
the initial fetch to 100MB.

http://www.squid-cache.org/Doc/config/delay_parameters/

# One pool
delay_pools 1

# first pool of type 2 (individual IPv4 address buckets)
delay_class 1 2

# network aggregate. unlimited.
# individual IPs:
# first 15MB unlimited := 15728640 bytes.
# after which 10Mbps := 1310720 _bytes_ per second.
#
delay_parameters 1 -1/-1 15728640/1310720

# all traffic for everybody gets this restriction.
delay_access 1 allow all

Only if the traffic normally goes through Squid AND your delay_access
rules are written in a way that catches it.

Instead of "allow all" you could do this if you wanted:
   delay_access allow !localWebsite
