Iframe solution

Hi there, I am a bit unclear on this answer.

From my understanding of the question, the parent product which hosts and integrates PDF.JS Express is white labelled, not PDF.js Express itself.

I would therefore like to confirm the answer to this question:

Example : The parent page loads from (http://company.com/) and in the page we have an iframe tag which opens (http://parent.com/) in which we load pdfexpress.js will this solution work?

We also face a situation where our SaaS product allows client to enable their own custom domain. As such, we are wondering whether we can still host on a single domain, ours, which would always load the web viewer, while it comes up iframed in client specific domains.

We have been discussing with PDFTron, and the pricing gap is not viable for us (x 4-5), especially given this is our only potential challenge with pdf.js express, so I would really like to get clarity on this point.

Thanks in advance
