Mixing
Difference between using XHR and script src
I saw this issue in Chrome, but will love to hear your answers about other browsers as well.
A script to domain thirdparty.com has been called from a website X (I call the script from js, not through the HTML).
<script src="http://www.thirdparty.com/example"></script>
I see that time after time this script is being queued before downloaded.
When I changed the call to the script to an XHR call (with eval), the script was downloaded without being queued first.
Can you please explain this issue to me? is it only a coincidence?

I don't think you can access the xhr results andevalthe text if it's a thirdparty domain script.

@Bergi, I am the third-party owner, and I can ask the developer of website X to add me to his webpage by script src or by adding an XHR + eval.

Thanks to some clever colleague, I have found these resources that describes the different resource priorities of a browser:
https://developers.google.com/web/fundamentals/performance/resource-prioritization
https://css-tricks.com/the-critical-request/
https://medium.com/reloading/preload-prefetch-and-priorities-in-chrome-776165961bbf
Based on these links - XHR is having a higher resource priority than script src.
