I'm interested in this. What's the CRDB equivalent of onBeforeRequest()?
I'm interested in that even tho this is factually correct, it's ignored / downvoted because it goes against the prevailing narrative. Discourse here can be pretty 1 dimensional, it's more like a confirmation bias machine / echo chamber, than a discussion. Just like the rest of the net, no matter how 'smart' the people here are. The same behavior pattern occurs here as everywhere else.
It would be interesting if this can be solved in discussion forums of the future.
I did find it, it's called setRequestInterception(). It's marked as experimental, and has a note that it disables caching, but there's some debate as to whether it actually does.
