Url alias is case-insensitive while adding but case sensitive while navigating

On my site I have a page that has the alias, "mypage". I can view this page by navigating to "mysite.com/mypage" but it fails to load when I navigate to "mysite.com/myPage" (the 'p' has been capitalized).

From what I know about apache and php I can tell that the issue is that in drupal the url is case-sensitive. FIne.

So I decided to add the alias "myPage" to point to "mypage" or "node/122" but when I tried to add the url alias I received this error, "The alias myPage is already in use." If url aliases are case-sensitive then the alias is *NOT* already in use. If drupal is interpriting the page url case sensitively then the path module should not prevent "myPage" from being added if "mypage" exists, correct?
