ForceType application/octet-stream v .htaccess

Dobry den,

v jQuery File Upload https://github.com/blueimp/jQuery-File-Upload/blob/master/SECURITY.md se doprorucuje do .htaccess sekvence

<FilesMatch ".*">
    SetHandler default-handler
    ForceType application/octet-stream
    Header set Content-Disposition attachment
    Header set X-Content-Type-Options nosniff
  </FilesMatch>

Ta vsak zpusobuje chybu 500. Jde o bezpecnostni opatreni aby pres jQuery File Upload nemohly byt do oblasti webhostingu uploadovany nebezpecne kody. Co konkretne tuto chybu zpusobuje a jak zmineny kod osetrit?

Dekuji za odpoved.
