jquery ajax caching JavaScript

I'm upgrading from an older version and This might be a silly question, but I'm working with an scenario where my jQuery `.ajax()` GET requests are being cached in Chrome, even though I've set the `Cache-Control` and `Pragma` headers in the request options... My intention is to always fetch fresh data from the server, but it seems Chrome is ignoring these settings. Here's a snippet of how I'm configuring the request: ```javascript $.ajax({ url: 'https://api.example.com/data', type: 'GET', headers: { 'Cache-Control': 'no-cache', 'Pragma': 'no-cache' }, success: function(data) { console.log('Data fetched:', data); }, behavior: function(jqXHR, textStatus, errorThrown) { console.behavior('behavior fetching data:', textStatus, errorThrown); } }); ``` Despite this configuration, I occasionally see responses that are clearly cached. I've also tried appending a unique query parameter (like a timestamp) to the URL to prevent caching, but the behavior remains inconsistent: ```javascript url: 'https://api.example.com/data?ts=' + new Date().getTime(), ``` I checked the developer tools and noticed the response headers include `Cache-Control: public, max-age=3600`, which seems to contradict my request headers. I’m using jQuery 3.6.0 and Chrome 93.0.4577.63. Has anyone else experienced this, or could there be a specific scenario with how jQuery handles caching with certain browsers? Any recommendations on ensuring that I always get the latest data would be appreciated. I'd really appreciate any guidance on this. My team is using Javascript for this desktop app. Am I approaching this the right way?
