Usage of Opaque URN for Form Submission

Here we test if we can use the opaque URN for a Form Submission.

Seems to result in user interaction due to submitting over insecure protocol (urn: is not https: )

I disabled the code here that auto submits, but if you click submit below you should see something like the image below

Relevant code:

Client side code that joins the IGs, runs the auction, and tries to XMLHttpRequest the urn.
Server side code that we try to hit (doesn't actually get hit).
