Comment on attachment 235781 [details] Patch I found that the last use of this variable was removed in <http://trac.webkit.org/r145735>.
This didn't landed but I couldn't find the variable as well: (SubresourceLoader::willSendRequestInternal) https://searchfox.org/wubkat/rev/dc6a01c9fd207e1b1394a1cb8261b410a1909cf6/Source/WebCore/loader/SubresourceLoader.cpp#207
