Workflow in an iframe

KNIME Server
1

Hi,
We are trying to embed a KNIME workflow inside an iframe but running into 404 and 403 errors. We have configured our server for CORS as well as created the token for the workflow to be embed, but most of the times we are getting these errors and on rare occasions the workflow will actually load and work.
Has anyone else managed to get the workflow to run correctly in an iframe?

Hi Willem,

this is a security feature that by default prevents KNIME WebPortal from sending session cookies to a user that is browsing a third party website. To enable embedding data apps in iframes, a small configuration change to our cookie handling is required. The details are found here:
https://docs.knime.com/latest/server_admin_guide/index.html#_embedded_data_apps_in_iframe

Kind regards
Marvin
