If your Zen Cart store is "http://somedomain.com/" then you can either set "RewriteBase /" (note the space) or comment out the RewriteBase line (as it is not needed).
If your Zen Cart store is "http://somedomain.com/zencart" then you would set "RewriteBase /zencart/" (note the trailing / for a directory).
If you are doing something out of the ordinary, you will need to adjust the mod_rewrite directives accordingly. The above assumes a standard web hosting configuration where the relative path for physical files is the same as the relative path in the URL (and HTTP / HTTPS are served from the same location and relative web path). 95% of modern web hosting configurations are done this way (when you have a SSL certificate for your domain).
