DRAGON_URL setting is undocumented

[akats]

In a production environment, it is recommended that Swampdragon runs on a subdomain of the site. The variable DRAGON_URL must point to that subdomain. This isn't documented in either the blog post on deployment, nor with the other settings. Would it be possible to take that blog entry, add this information as one of the steps, and copy to the documentation?

Because we want to separate our Django instance from our SwampDragon instance, we add a subdomain so we can run this on port 80 (we want to use the same port as http to prevent firewall issues).

I think this is the blog post you are referring?

Yeah, that's the post. I think it would help if it referred to the names of the configuration variables, like DRAGON_URL.

Hello,

I also noticed while doing your excellent tutorial http://swampdragon.net/tutorial/part-1-here-be-dragons-and-thats-a-good-thing/ that I needed to add DRAGON_URL to settings in order the app to work.

This wasn't mentioned in tutorial and without that setting I got following error:

Interesting project by the way! :)
