Getting an error page when looking up particular domains

[bvanrijn]

Go to https://jsonp.afeld.me/?url=icanhazip.com.

The server (probably) crashes and a CloudFlare 502 error page is shown. JSONProxy starts working after a few minutes.

Maybe this is happening because icanhazip.com contains no valid JSON? I will try with some other sites and post an update here.

Non-resolvable URLs knock it down as well.

I even tried google.com and example.com, they worked and showed me their respective HTML pages.

None of the aforementioned domains failed locally (i.e. responded with an error page, instead of JSON) on Git master branch, but they did return status code 502. It seems CloudFlare implicitly assumes the site's broken once it sends a 502.

Then this is an issue with CloudFlare and not JSONProxy...

For CloudFlare, however, it seem like it's a feature, not a bug.

Would it make sense to always send a 200 OK response, and have the client figure out if something went wrong? (i.e. the error key is present)
