hi,
   Im managing a bilingual website.

Two languages can be used with URL like this.

www.website.com/product/computer.html?lang=en
www.website.com/product/computer.html?lang=jp
Also
www.website.com/product/apple/laptop.html?lang=en
www.website.com/product/apple/laptop.html?lang=jp


No other pages/url_patterns in the website needs Language settings.
I need a redirect rule to use with this 2 patterns with language in domain part of URL.

en.website.com/product/computer.html
should be processed internally as
www.website.com/product/computer.html?lang=en

and

jp.website.com/product/apple/laptop.html
should be processed as
www.website.com/product/apple/laptop.html?lang=jp

As you can see
domain part en/jp should become ?lang=en/jp
and should be valid with this URL patterns
xxxx/product/xxxxxx
AND
xxxx/product/apple/xxxxx

RewriteRule can be in httpd.conf OR htaccess.

Since Im not good at this RewriteRule I request you to have this as simple as possible.

Thank you for all in advance.

Try:

RewriteEngine On
RewriteCond %{QUERY_STRING}  !lang=[ej][np]  [NC]
RewriteCond %{REQUEST_URI}  ^/product/         [NC]
RewriteCond %{HTTP_HOST}      ^(en|jp)\.         [NC]
RewriteRule  .*   %{REQUEST_URI}?lang=%1      [L,QSA]

Can you explain these lines ?

RewriteCond %{QUERY_STRING}  !lang=[ej][np]  [NC]
RewriteCond %{REQUEST_URI}  ^/product/         [NC]
RewriteCond %{HTTP_HOST}      ^(en|jp)\.         [NC]

Sure:

# Turn on the Apache Rewrite Engine
RewriteEngine On    

# If the URL DOSE NOT contain a CGI-Parameter of "lang=XX", where XX is either {en, ep, jn, jp},  ignoring case (NC = NOT CASE sensitive)
RewriteCond %{QUERY_STRING}  !lang=[ej][np]  [NC]

# AND If the URL starts with "/Product/", in any case
RewriteCond %{REQUEST_URI}  ^/product/         [NC]

# AND If the URL starts with http://en.   or   http://jp.
RewriteCond %{HTTP_HOST}      ^(en|jp)\.         [NC]

# THEN Add (QSA = Query String Append) a "lang=XX" to the URL, and stop manipulating the URL (L = LAST rule)
RewriteRule  .*   %{REQUEST_URI}?lang=%1      [L,QSA]
