No, I think Soeren is right. The browser requested .../bar/AKS which
was not found. mod_speling then searches .../bar (which exists) and
finds aks and AKs. If mod_speling were to return "../AKs" then the
browser would see .../bar/AKS/../AKs -- yes, it would probably strip
away the "AKS/../" part, but anyway, .../bar/AKS/../AKs is not really a
valid path. The better approach (which is used by mod_speling in the case
of a single match anyway) is a redirection to the absolute path.

Soeren, can you please test if the appended patch fixes it for you?

The patch contains:
  * a fix to the absolute vs. relative HREF generation, as by your proposal
  * a fix for mod_speling doing the wrong thing for a request to "/" in
    some rare situations (esp. when mod_mime is not compiled in)
  * indentaion fixes a la apache style guide.
