It's 2023, and I am honestly perplexed that sending custom request headers is still a pain-in-the-ass with some #JavaScript #web frameworks.
Custom request headers were supported by *#ActionScript* in 2005.
(walks away grumbling to self about javascript frameworks stuck on an innovation threadmill, reinventing #ModelViewPresenter, #DataBinding, and component frameworks over, and over, and over, and over again)
