init rewrite engine with requested uri /connect_4-3d // THIS DIRECTORY EXISTS
applying pattern '^/(.+)' to uri '/connect_4-3d'
RewriteCond: input='/connect_4-3d' pattern='!-s' => matched
RewriteCond: input='/connect_4-3d' pattern='!-d' => matched  // WHY DOES IT MATCHED SINCE IT IS A DIRECTORY ?
cache lookup FAILED, forcing new map lookup // WHY DOES IT DO THAT ?
map lookup FAILED: map=ispacemap[txt] key=connect_4-3d
rewrite '/connect_4-3d' -> '' // AND THAT IS THE DEFAULT VALUE

How can I not use '' as default value but instead the same pattern ?
