mod rewrite

Dobry deň.
Potreboval by som aby sa stranka zobrazovala ako www.mojastranka.sk/nadpis-stranky.html
a nie ako www.mojastranka.sk/post/nadpis-stranky.html

Keď vymažem "post" tak to nefunguje poradte čo treba ešte upraviť. ďakujem

Keď vymažem "post"
ODKIAL HO VYMAZES?
Z prveho riadku?
$htaccess .= "RewriteRule ^post/(.*).html(.*)$


hej presne to keď vymažem tak to nefunguje a potrebujem tam ešte niečo upraviť len neviem čo
