I really don't think there are many other options here besides using _wcsnicmp.
Why not just use that? This is the only place where urlLegacy is used.

[Eric, 2015/02/27 14:26:56]

I changed only the code relevant to the DEBUG_GENERAL statement. I wasn't even
looking at the remaining uses of that variable.

We could change it here if you'd like, even if it's not strictly related.

     DEBUG_GENERAL(L"Not injecting");
