I just watched it do two GETs on one connection:

Requests:
GET / HTTP/1.1
Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, */*
Accept-Language: en-us
Accept-Encoding: gzip, deflate
User-Agent: Mozilla/4.0 (compatible; MSIE 4.01; Windows NT)
Host: localhost
Connection: Keep-Alive

GET /Admin/lgmast.gif HTTP/1.1

Referer: http://localhost/
Accept-Language: en-us

There were three GETs altogether, and one went by itself on a second co=
nnection.
I haven't seen MSIE put more than two requests on a connection.
