Hi-  
This is a newbie question:

I started an http server:

myserver = HTTPServer.new(:Port =\> 8080,  
:DocumentRoot =\> Dir::pwd + “/temp”)  
myserver.start

Q: how do I display the current document root?  
man thanks  
Max

HTTPServer is not a Rails class. I think you’re on the wrong forum.  
Maybe try the Ruby forum.

You are correct. This is plain Ruby class as I am learning the basics  
but even so, under Rails, how can I display document\_root?  
If there a config variable I can display?  
thanks

For Rails apps you have Rails.root which give you the root of the Rails  
project. The actual web server document root would then be  
“#{Rails.root}/public”
