Help me to redirect 301

My urdu is

www.mydomain.com/hello/.html

i want to make it like that www.mydomain.com/hello.html

i can do it through wordpress premlink option

but i does not want to loss my indexed result at google
plz let me know which code is used?



I mean when some one click on www.mydomain.com/hello/.html it should automatic redirect to www.mydomain.com/hello.html

 

You can search in google

 

i tried alot like

Redirect 301 /olfpage.html www.myweb.com/newpage.html but it is not working

 

In the .htaccess in the root of your web add the following lines after the rewrite engine is set to ON and before the code inserted by WordPress:

RewriteCond $1 hello/\.html [NC]
RewriteRule (.*) http://www.example.com/hello.html [R=301,L]

substituting "yourdomain.tld" for example.com above.

 

I used this guide when I did a redirect it on my site http://www.internetbasedmoms.com/seo/301-redirect.html

 

I tried the following code

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond $1 real-inspiration/\.html [R=301,L] [NC]
RewriteRule (.*) http://www.hulsestrength.com/real-inspiration.html [R=301,L]
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress

and its work, when i added some more links like that, the page show SERVER error

Internal Server Error

And now it is no more working, even the code which worked
