A little recap of what I have done ... and then my questions Q1, Q2 and Q3
1 - I developed a RoR app that I deployed on Heroku.
2 - I bought a domain name at GoDaddy:
3 - I am using Zerigo addon as for the DNS
heroku addons:add custom_domains heroku addons:add zerigo_dns:basic
4 - Added my domains in Heroku
heroku domains:add biowattsonline.com heroku domains:add www.biowattsonline.com
heroku domains:add calculator.biowattsonline.com
Q1: Where do we configure the forward to http://biowattsonline.com/biogas_calculator ?
5 - Configured GoDaddy adding the Zerigo domains
In the Nameservers section
a.ns.zerigo.net b.ns.zerigo.net c.ns.zerigo.net d.ns.zerigo.net e.ns.zerigo.net
The GoDaddy DNS section is empty: "Not hosted here"
Ok this works all fine ... http://biowattsonline.com is correctly found
6 - Subdomain forward
I want calculator.biowattsonline.com to be forwarded to biowattsonline.com/biogas_calculator
Q2: So I created the forward in GoDaddy ... but is that correct?
7 - GoDaddy email
Q3: I have one free email account with go GoDaddy, only now that I am using Zerigo I don't know how configure GoDaddy to make it work again?... because it work with the default values
Any ideason Q1, Q2 and Q3?
