Redirect of old webpage to new webpage.

Hi Tom,

I notice that the following redirect instruction in the file *.htaccess under my root folder,

Redirect 301 /services/product-design-and-development/ /electronic-integration

Can redirect from
http://www.pic-control.com/services/product-design-and-development/
to
http://www.pic-control.com/product-design-and-development/

However, it cannot redirect from
http://www.pic-control.com/services/product-design-and-development/index.html
to
http://www.pic-control.com/product-design-and-development/

Is there any way I can have both URL (with or without /index.html) redirect to the same URL?
Appreciate your help.
Thank you.
