These changes seem completely separate from what the bug claims to be fixing. I think you should split them into a separate bug/patch.

I think using a Vector<UChar> and String::adopt would be more efficient, since you won't have to copy the whole string at the end.

It would be clearer to have an early return if the second call to HttpQueryInfoW fails.

It might be nicer for this function to be a non-member function with internal linkage.
