I have my domain name example.com from domain registrar BigRock, which also provides me the DNS management panel.
My application is hosted at Heroku at example.herokuapp.com.
Domain Settings at Heroku:
bash-3.2$ heroku domains
=== MyApp Domain Names
*.example.com
example.herokuapp.com
example.com
www.example.com
In my DNS Management panel, I have 0 A records, 1 MX records for Hotmail and 1 CNAME record for www.example.com.
I know about the problem with Naked domains and A-records with Heroku.
I have gone through these:
1. StackOverflow ques - How to setup DNS for an apex domain (no www) pointing to a Heroku app?
2. Heroku DevCenter - Custom domains - set up root domain
3. Heroku DevCenter - Apex Domains
The above links and many others point towards 2 solutions:
- Using ALIAS or ANAME records by DNSimple/ DNS Made Easy
- If your DNS provider does not support such a record-type, and you are unable to switch to one that does, you will need to use subdomain redirection to send root domain requests to your app on Heroku.
Since, I couldn't find such records on BigRock DNS Management Console. There were only these records - "A, AAAA, MX, CNAME, TXT, SRV and SOA".
Accordingly, I have setup "Domain Forwarding" for my domain. But, it only gave me option to provide "Designation URL where you wish to forward requests for www.example.com and example.com".
Now, If I do
bash-3.2$ host example.com
example.com has address 173.194.16.11
example.com mail is handled by 15 888379351a9a.pamx1.hotmail.com.
and
bash-3.2$ host www.example.com
www.example.com is an alias for example.herokuapp.com.
This does solve the naked domain problem. But other subdomains like xyz.example.com are still not redirected to www.example.com, because
there is no mention to redirect all subdomains i.e "*" to any other designation in the "Domain Forwarding" section on BigRock DNS provider.
So, my question is how can I solve this problem of redirecting sub-domains?
Another Query Related to SSL -
Here in the Heroku Devcenter - subdomain redirection, it says that "However, be aware that, using this method, a secure request to the root domain, e.g., https://example.com, will result in an error or warning being displayed to the user."
Is there any way of fixing the above issue, or do I have to switch to DNSimple or DNS Made Easy to use the ALIAS or ANAME records services they provide?
UPDATE:
On further digging, I found this SO ques - Rails Manually redirecting from Naked Domain, which suggests using:
Is this a better way?
