.htaccess

Hi,

I am a new user of WP and I want to replace my old html pages with WordPress. How to redirect my old html pages to new WordPress pages in .htaccess?

Example:
domain.com/portfolio.html -> domain.com/portfolio/

Is that correct?

Redirect permanent domain.com/portfolio.html domain.com/portfolio/
order deny,allow

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ – [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

I have been trying many times but it doesn’t work. Page not found error 500.

Thankx in advance
