Do modern browsers still limit parallel downloads?

In this Yahoo article from 2007, the authors argue that static assets should be split across different hostnames because browsers follow a suggestion from the HTTP/1.1 spec to limit parallel downloads to two per hostname.

My question is, do modern browsers still follow this limit? Using firebug, I noticed that my browser is downloading many more than 2 files in parallel.

Solution

  • Microsoft till IE 7 is limited to two IE 8 and 9 to six. Firefox is limited to six. There is a fix out from ms to modify all to ten: http://support.microsoft.com/kb/282402

    you can asume that all modern browsers have a default limit of six
