php - htaccess rewrite non html request -

i've migrate dynamic .asp site static site using sitesucker osx app... works done if access directly!

old url:

http://www.mysite.com/content.asp?l=1&idmen=158‎

new url:

http://www.mysite.com/content.asp-l=1&idmen=158‎.html

i page not found old referral inbound links (google, yahoo etc...)

i like, using .htaccess, redirect links not contains ".html" permanent redirect html page...

i've tried not work:

rewriteengine on rewritecond %{request_uri} !\.html rewriterule ^(.*)$ $1.html [r=301,l]

many frankie

as per examples if want modify query string need rule in document_root/.htaccess file:

rewriteengine on  rewritecond %{query_string} !\.html$ [nc] rewriterule !\.html$ %{request_uri}-%{query_string}.html? [l,r=301,ne]
