Reduce network traffic by specifying a checksum attribute

[graph]

What problem are you trying to solve?

Reduce network requests and transfers

What solutions exist today?

currently CDN's are used. Different websites will refer to jquery from a popular CDN thereby reducing network traffic overall and faster load times when a person visits different websites that use the same CDN.

How would you solve it?

add a checksum tag to various elements such as script, link, img. This way the same file can be used across different CDN's. The checksum tag will start with the algorithm such as sha256, sha512, etc.. followed by a ":" and then the sum.

<script ... checksum="sha256:b94d27b9934d3e08a52e52d7da7dabfac484efe37a5380ee9088f7ace2efcde9">

This cannot be used to reduce network traffic because it causes privacy leaks. https://hillbrad.github.io/sri-addressable-caching/sri-addressable-caching.html#history_leaks
