Ništa komplikovano - u .htaccess staviš:
Kôd:
LimitRequestLine 128
i nijedan URI duži od 128 karaktera neće proći. Default vrednost je 8190.
Moraš da budeš pažljiv i da ne staviš limit koji je previše nizak, da bi legitimni zahtevi mogli da prođu. Takođe, postoji mogućnost da admin ne dozvoljava korisniku da izmeni ovo podešavanje.
Nije na odmet ni da u .htaccess staviš ovaj kôd (preuzet sa
