[jQuery] What does this do - transport.setRequestHeader("connection", "close")

[jQuery] What does this do - transport.setRequestHeader("connection", "close")


I've been implementing Dan Switzer's autocomplete plugin on my site and
I have everything sort of working (thanks Dan!) but ran into an issue
with authentication. My site uses Windows Integrated Authentication (on
IIS) and every Ajax request kicks off a login prompt...
Dan found this:

I replaced my compressed jQuery script with the source and commented out
that line:
// transport.setRequestHeader("connection", "close");
Which seems to have solved this issue. But I want to make sure this
doesn't screw up anything else??
Also - how can I re-compress my source with this modification included?
Thanks,
Jim
