That sounds like it would do the job. But I am entirely new to the world of .htaccess and what looks like fiendish redirect syntax. I found this on the web to remove a index.html prefix:

# redirect to remove "index.html" prefixes from requested URLs
RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /index\.html/.
Rewriterule ^index\.html/(.+)$ www.example.com/$1 [L,R=301]

So, I would want someting similar to that I guess - do I replace www.example.com in the above with my own site url?

Any how to remove the trailing .html from the old url?

Thanks for any help

My previous site used SH404 and that generated urls like:

amber-green-consulting.co.uk/ag/index.ph...-green-products.html

I am now using JoomSEF on my new site and the equivalent url is this:

amber-green-consulting.co.uk/ag/products/amber-green-products

I have created a 301 redirect in JoomSEF to point the old url to the new one:

Moved from url: index.php/products/amber-green-products.html
Move to url: products/amber-green-products

But this does not work - I get 404 error when using the old url.

I think its to do with the index.php in the old SH404 url - if I create a 301 redirect without this, it works ok. Trouble is old links and search engines have those old urls whicih include index.php/

Any ideas?
