[x3d-public] X3D agenda 24 APpril 2020: Cross-origin resource sharing (CORS)

[Don Brutzman]

As reported in last week's minutes, this week am planning to review

====================================
Cross-origin resource sharing (CORS)
https://en.wikipedia.org/wiki/Cross-origin_resource_sharing

Cross-origin resource sharing (CORS) is a mechanism that allows restricted resources on a web page to be requested from another domain outside the domain from which the first resource was served.[1]

A web page may freely embed cross-origin images, stylesheets, scripts, iframes, and videos.[2] Certain "cross-domain" requests, notably Ajax requests, are forbidden by default by the same-origin security policy. CORS defines a way in which a browser and server can interact to determine whether it is safe to allow the cross-origin request.[3] It allows for more freedom and functionality than purely same-origin requests, but is more secure than simply allowing all cross-origin requests.

The specification for CORS is included as part of the WHATWG's Fetch Living Standard.[4] This specification describes how CORS is currently implemented in browsers.[5] An earlier specification was published as a W3C Recommendation[6]
====================================

Goals:

a. collect key references, especially for various browsers,
b. synopsize challenges and alternatives for portable content,
c. discuss current practices in X_ITE and X3DOM,
d. discuss what changes might be needed (if any) in X3D Examples Archives,
e. identify any related issues,
h. initial assessment regarding whether this should be addressed in X3D4 Architecture specification.

Zoom room coordinates are now linked via the Web3D Calendar.
