Is Mapserver case sensitive for the WMS parameters

[Yewondwossen Assefa]

   All code in Mapserver regarding formats are case insensitive AFAIK
(for the Parameter and even the value).
   Until wms version  1.0.7, Mapserver returned in the Capabilities, the
format name ("<PNG />" "<GIF />", ...) but for more recent version It
returns the mime type.
  I was not really not able reproduce this error with quick tests usiing
wms 1.1.0 and wms 1.1.1.
