Actually he's right, the HTTP v1.1 standard does specify a maximum number of connections. I believe it's 4 but it could very well be 2, I'm not sure & I'm too lazy to go look it up because it's 1:00am and I really don't give a shit mines set at 10

Correction: I'm not to lazy to look it up, so here tis...
In accordance with Request for Comments (RFC) 2068, IE 5.0 and later limit the number of concurrent downloads to one server. HTTP 1.0-based servers are limited to four sessions, and HTTP 1.1-based servers are limited to three sessions, one of which is queued.
