I read extensive parts of the CORS specification and it is indeed teflon (and just as toxic as teflon as well). The spec is full of exceptions and leaves many choices to the browser vendors.
To truly understand CORS, you have to fundamentally understand 'the origin' as a security and execution context. Sharing means that content normally intended for another origin is shared with the initial origin.
Perhaps that is blatantly obvious and you are more confused by the myriad of headers, exceptions and lifetime. In that case, I propose to read more of the spec.

- klodolph 7y agoBut Teflon is non-toxic and biocompatible. You can eat it, your body is unable to process it or break it down and it will pass through your digestive system. You can coat surgical instruments and medical implants with Teflon. (Above 300°C Teflon will generate toxic fumes, but then again, so will wood.)

- hn23 7y agoI have read $somewhere that it accumulates in testicles. And why would I coat surgical instruments? Edit: Just one article how healthy Teflon is: https://fortune.com/longform/teflon-pollution-north-carolina/ https://fortune.com/longform/teflon-pollution-north-carolina...
- klodolph 7y agoThat is an article about byproducts of Teflon manufacture.
- iforgotpassword 7y agoStudies funded by companies selling Teflon products say 300 degrees. Others conclude it happens at temperatures as low as 200 which you can easily reach while cooking. Anyways I'm almost always using plain old steel pans and pots. There are very few things that stick so badly I resort to the one Teflon pan I have.
- whatshisface 7y agoWatch out: some types of stainless steel can leech enough nickel to approach the safety line.
- justinclift 7y agoWhich safety line? :)
- edejong 7y agoWith regards to the toxicity, I was referring to the Intercept [1] article which appeared last year. It's a long read and details the manufacturing process. Nevertheless, where there is smoke... [1] https://theintercept.com/2018/07/31/3m-pfas-minnesota-pfoa-pfos/ https://theintercept.com/2018/07/31/3m-pfas-minnesota-pfoa-p...
