While strolling with my canine companion earlier, I stumbled upon the notice on the right. After recently examining yet another middleware/HTTP header dilemma (the Next.js concern that was disclosed this weekend) [1], I decided it was time to compose a piece regarding HTTP headers. We are all familiar with HTTP headers. However, it seems that some individuals are not as knowledgeable about them as they ought to be. Similar to this notice, proxies and other middleboxes rarely prevent risky practices.
