Simple jQuery cache that routes ajax GET calls via the browser's session storage. A one line include.

NB Written with the help of ChatGPT, so you know, robot warning.

The use case I have in mind is fetching the same file multiple times via AJAX calls, where there is limited opportunity to refactor the code to reduce the number of requests, e.g. dynamically generated code.

Makes use of ajaxPrefilter to monkey patch $.ajax calls. It uses the browser's session storage API to try cache the data being fetched, as well as implement a simple locking mechanism to avoid parallel calls racing to fetch from source.

Should be as simple as including the following script tag in your project of choice:

<script src="https://cdn.jsdelivr.net/gh/Gordonei/really-simple-jquery-cache@main/jquery-cacher.js"></script>

I haven't really tested this with anything except GET calls that return JSON. I've tried to put a bit of defensive coding in to limit its use to that scenario.
