Long story short: Can you cancel a POST or GET REST request once it's sent?
Situation: This is not a site that I'm developing, but if possible, I want to recommend that the developers cancel a POST request that populates search results in real-time as the user types characters into the search box.
Scenario: The user types a few characters, stops for a second, then types more characters.
Issue: The app sends a POST request once the user stops typing for 400ms. When the user starts typing again, it sends another request.
Repercussion: First and foremost, this takes extra resources from the system, unnecessarily. Aside from that, the real-time search results will be populated by whichever request takes longer to process. Typically, the first request will return results faster than the second request, and be trumped by the second request, but that's not always the case.
