How to find source of 301/302 redirect loop? Heroku GoDaddy Zerigo
- by user179288
this should be a relatively simple problem but I'm having trouble.I hope this is the right forum to post on as I've seen people get booted off stack-overflow for this sort of thing. I've setup a web app on heroku (cedar stack) at my-web-app.herokuapp.com and I'm trying to direct my-domain.com and www.my-domain.com to it.
As per instructions on the heroku documentation, I've set my-domain.com to redirect (forwarding) to www.my-domain.com and then set a C-Name from www.my-domain.com to my-web-app.herokuapp.com. But the C-Name doesn't seem to be working right and is sending back to my-domain.com, causing a loop and I can't work out why.
I first configured these setting at GoDaddy.com where I registered the domain but then tried to avoid the problem by using Heroku's Zerigo DNS add-on, setting the nameservers on GoDaddy to the ones given for Zerigo. However the problem remains.
Here is the output from dig for my-domain.com ("drop-circles.com"):

And from Fiddler if I use the inspector when I try either address I get a series of requests, with the my-domain.com ("drop-circles.com") looking like this:

And the www.my-domain.com ("www.drop-circles.com") looking like this:

Any and all help would be greatly appreciated. If it is not at all obvious from these readouts what it might be could someone at least tell me which company GoDaddy, Zerigo or Heroku should I go to for support since I don't really know enough to be able to say where the problem lies. Thank you.
