Description:

Requests to documents sometimes cannot be served by the core apache server
because the request was misspelled or miscapitalized. This module addresses
this problem by trying to find a matching document, even after all other
modules gave up. It does its work by comparing each document name in the
requested directory against the requested document name without regard to
case, and allowing up to one misspelling (character insertion / omission /
transposition or wrong character). A list is built with all document names
which were matched using this strategy.

If, after scanning the directory, * no matching document was found, Apache
will proceed as usual and
return a "document not found" error.
* only one document is found that "almost" matches the request, then
it is returned in the form of a redirection response.
* more than one document with a close match was found, then the list
of the matches is returned to the client, and the client can select the
correct candidate.
