Description Brian Nicholson (:bnicholson) 2012-06-20 15:35:40 PDT
<bz> but in any case, the upshot is that there is no valid docshell loadtype that has both flags
<bz> and docshell uses integer loadtypes instead of flag bits
<bz> so it's all kinda broken
<bz> any time you want to do a new flag combination, you have to explicitly allow it...
<bz> And in particular, nsDocShell::DoChannelLoad does a switch, not a bit check

This patch works for me, but I had to guess on a few things:
- whether this should be prefixed with LOAD_NORMAL or just LOAD
- what nsIDOMPerformanceNavigation type this should be considered as

This change is for the "Request Desktop Site" feature on mobile (bug 766406). If changing from a mobile->desktop version of a page, we want to make sure we aren't showing the cached mobile page, and we also don't want the same URL to be in the history twice.
