# -FrontPage-

IndexIgnore .htaccess */.?* *~ *# */HEADER* */README* */_vti*

<Limit GET POST>
order deny,allow
deny from all
allow from all
</Limit>
<Limit PUT DELETE>
order deny,allow
deny from all
</Limit>
AuthName www.example.gr
AuthUserFile /home/example/public_html/_vti_pvt/service.pwd
AuthGroupFile /home/example/public_html/_vti_pvt/service.grp

RewriteEngine on
RewriteRule .*\.(chat)$ http://www.example.gr/chat/chat.html [R,NC]

i change the AuthUserFile && AuthGroupFile the path but is doing nothing i have the same problem

Invalid command 'RewriteEngine', perhaps mis-spelled or defined by a module not included in the server configuration

can anyone help me?

The error message is quite helpful there; you need to edit your server configuration to include mod_rewrite. Look in httpd.conf for that, then restart apache.
