Current behavior

When opening a plnkr from your site the plnkr never loads and console errors are thrown.

Expected behavior

The plnkr loads

Minimal reproduction of the problem with instructions

1. Open a plnkr link from your documentation page.
2. Observe the endless spinner.
3. Open the console and see the following errors:

What is the motivation or use case for changing the behavior?

Trying to play with our examples before I implement them in my code.

We are currently working on fixing this, but meanwhile clearing the cache is the way to go.

The problem should go away by itself as the browser cache expires. Let us know if this is not the case.

[lslocum]

Clearing the cache is no longer working for me. It worked the first day, but I have tried several times today. I opened the site in incognito mode and with IE 11 (which should have nothing cached because I never use it) and still get the console errors and an endless spinner.

@lslocum thanks for getting back. I think we finally figured it out - we needed a "Vary: Origin" header to make sure the browser caches the correct origin.

You might still need to clear the cache once more or wait for it to expire (4 hours). But after that, it should be fine.

[tsvetomir]

Okay, that was a bit rushed - the issue is still reproducible in Chrome.

[tsvetomir]

Fixed at last. Thank you for the patience.

[lslocum]

It is working for me now. Thanks!

I am experiencing this exact error now in Chrome.

@aliawilkinson can you share the plunkr URL?
