No! don't listen to Fred, you may loose your wiki :-)

url_prefix has nothing to do with your wiki name, and they should never 
be the same.

url_prefix is the url prefix of moin static files (css and images). For 
example:

	http://yourdomain/wiki/modern/css/screen.css

While your wiki url look like this:
	
	http://yourdomain/mywiki/pagename

Back to the question, how do you set this value? Just leave this as is, 
"/wiki". This value is used by moin when it creates links to static 
files (If you look into the html source, you will find those urls).

Now, what Apache is going to do with 
"http://yourdomain/wiki/modern/css/screen.css"? there is no "wiki" 
directory in your document root. Thats why you need the Alias 
configuration:

	Alias /wiki/ /usr/share/moin/htdocs/

This tell Apache that any url that starts with /wiki/, should be served 
from the path "/usr/share/moin/htdocs/". This path should be adapted to 
your installation.
