You saw more than I did. There was no mention of whether the limits
that the OP wanted to exceed were outbound or inbound connect limits.
"xp" doesn't actually describe much nor does "its connection" specify
outbound or inbound connects. I guess outbound. You guessed inbound.
The post was vague so the result is replies that are just as unfocused
as was the question.
The registry hacks only specify maximum outbound connects via HTTP and
HTTPS. That doesn't mean there is necessarily a web server at the other
end. Depends on the port used which doesn't have to be 80. Depends on
what process is listening on that port at the other end; for example,
some remote access tools use port 80 to get around corporate firewalls,
like TeamViewer. You only know the registry edits are for outbound HTTP
and HTTPS, not what is on the other end.
The workstation 10-connect inbound limit was set back in Windows NT 3.5,
not in a service pack for Windows XP. Read
http://support.microsoft.com/kb/314882 and you'll notice it refers back
to Windows 2000. Go read
http://support.microsoft.com/kb/122920 and
notice that goes back to WinNT3.5. It wasn't Service Pack 2 for Windows
XP that established that limit
