I'm looking for the way to log stuff in Internet Explorer Developer Console that preserve page refresh.
Under Google Chrome and Firefox's Firebug it's an option for that, but I could not find it under IE.
I'm using IE 9.
In IE Developer Cosole go to Tools -> Clear Entries on Navigate and uncheck what you want to stay in log.
In Internet Explorer 11 there is now a button ("Clear entries on navigate") which one must toggle for enabling/disabling the IE to clear the network logs on navigation or even http redirect.
MSDN: http://msdn.microsoft.com/en-us/library/ie/dn255004(v=vs.85).aspx
In Internet Explorer 11 there is a button that you can click to delete or preserve console logs on navigation. If you want to preserve your console logs, then just untick the button (highlighted red in my screenshot).
