Setup Plesk to have search engine friendly subpages?

[Lee Foot]

Hi we have a client who prefers to use our linux box over our Windows box (using Plesk 8.6.0) as he claims that Plesk will not allow him to use search engine friendly sub pages. (I.e www.example.com/about.htm) instead he gets a numerical ID instead. www.example.com/371283128.htm)

Is this an option that was can change from within Plesk to make our sub-pages URLs like our linux box and use plaintext instead of numerical values?

Any help GREATLY appreciated.

Lee.
