question about mongrel_cluster in ROR

[Varun Goel]

Hi all,
I wanna know one question about mongrel_cluster i do'nt know it's
silly question or not cos i am new in ror and apache also.
1: I run the command after configure the mongrel_cluster like
mongrel_rails cluster::start and it's shows that starting port 3000 and
starting port 3001.
Now please tell me that when i typed url http://localhost:3000/ and
http://localhost:3001/ i am getting error unable to connect why is it
...
For that i have to run server on 3001 and 3000 port or after runnning
this command by default it's run the server.
I am so confused please give me guidelines.........

Thanks & regards,
Varun Kumar
