Apache: Mod_rewrite

[soori]

We have a oScommerce site installed in the subfolder /catalog.

We want to hide the folder name 'catalog' from the URL. However, there is a dynamic Web site in the root folder.

Please guide me how to mask/ hide the catalog folder by modifying the .htaccess code?


Thanks in advance.
