Install mod_rewrite

[Connie]

you could test by defining a slug:

Code:

%parent%/%slug%.html

in the settings... do you get what you want?

If not, you try an online htaccess generator.

That is the best way because you can get results, check them and alter eventually in short time, without waiting for a suggestions, it allows to test without break...

so that you get a working rewrite at the end

you could test this one: http://www.htaccessredirect.net/
