if you don't patch the tcp stack, service pack 2, "sort of". HTTP/1.1
provides for pipelining requests via keepalives, so this is the
2concurrent requests per domain - and this is how the whole web works, -
unless you use many sub domains (3rd level domains) in your (x)html
markup, its not an issue for the individual.
However hitting the limit would be similar to a DoS but in web terms
this never really arises unless you are serving large files, because the
connection is over quickly, chances are anyone using XP is at home on
ADSL so the bandwidth issue crops up before the concurrent connection
limit anyhooo.

When you consider that this connection limit was introduced to help stop
worms proliferating, and that this is an exponential growth anyway, it
seems obvious that its fine to patch it back to more than 10!
