[TYPO3] Hide portion of URL

[Hervé Inisan]

Hi list!

I have a Typo3 site with RealUrl. Works fine.

The site is located in a subfolder (e.g. www.mysite.com/cms instead of
www.mysite.com)
Is there a way to hide the subfolder name (cms in the example) from the URL,
in order to simplify the URLs?

TIA,
