Potential CORS problems

[hauschka]

hey @gtj0

I wanted to know how you're handling cross-origin (CORS) problems when using the hosted version of DueUI (dueui.org) to control a printer.

Are you running into any errors?

Could you help me understand how you're handling this on the DueUI side?

Thanks,

The dueui.org server, the Duets and the DSF all send Access-Control-Allow-Origin: * headers and DueUI uses jsonp to retrieve it's config. I haven't seen any errors whatsoever. Are you having issues?

@gtj0 Not quite right, CORS headers are no longer provided by DuetWebServer unless you enable the corresponding option.

To do so, change UseCors in /opt/dsf/conf/http.json from false to true and restart DWS via sudo systemctl restart duetwebserver.

@chrishamm Ah. I hadn't been keeping up. Good to know. Thanks!
