The check-sensitivity flag does not mean what you think (I guess):
When set to false, Jigsaw expect the file system to be case sensitive,
hence it relies on the file system to distibguish between "/Admin" and
When set to true, Jigsaw expect directory listings to be in proper
case, and when a requested URL is not found, it lists the directory to
get the proper case, which is compared to the requested URL part.

So, whatever happens, if getting foo.GIF works, then getting foo.gif
will not work, however, as extensions are now case insensitive, both
foo.gif and foo.GIF will be indexed using either GIF or gif extension

URLs are specified as being case sensitive, that's why Jigsaw has it.
