It would be great if you created a test page with a bunch of images from different ports, and then watched them in Firebug Net Panel to see if the number of parallel connections exceeds the max. Please comment back here if you do so. @Guillermo: The best test is to do a test on your live traffic with JavaScript timing the page (see the Jiffy Web project).

How sure are you about that? My impression was that installing IE8 raises the simultaneous connections limit by changing a system-wide setting. Have you tested Firefox or Chrome on a fresh install of Windows that's never seen IE8? “Not all browsers are restricted to just two parallel downloads per hostname.”

Is there a tool or method i could use ( short of proto-typing) to test using 2 vs. 4 host manes for static images across my website? My testing is limited to only http requests as i would prefer to leave all of my assets for ssl under a single hostname I’ve been doing quite a bit of research regarding domain shredding.

With new browers that have 6 threads per domain, it's probably safe to stay with only one domain on SSL (and never more than two).

There are certificates that can handle multiple subdomains, but most don't. And if you don't have one, your user will end up with all sorts of warning messages about mixed resources and a broken 'padlock' symbol.

I think that in some cases could be possible to check the browser type and define dynamically the number of hostnames. The script has a time cost, but it reduce the DNS lookup time for newest browsers. Great article!
