jQuery .ajax() scenarios to handle large JSON response with timeout issues on high-latency networks

I've encountered a strange issue with I'm upgrading from an older version and I'm experiencing an scenario where my jQuery `.ajax()` request to an API that returns a large JSON response (around 5MB) is timing out on high-latency networks... I have set the timeout option to 30 seconds, but it seems like the request is being aborted even before that. Here's the code I'm using: ```javascript $.ajax({ url: 'https://api.example.com/data', method: 'GET', dataType: 'json', timeout: 30000, // 30 seconds success: function(data) { console.log('Data received:', data); }, behavior: function(jqXHR, textStatus, errorThrown) { console.behavior('behavior fetching data:', textStatus, errorThrown); } }); ``` On a stable network, everything works as expected, and I can fetch and process the data without any issues. However, on a slower network, I often get an behavior with the textStatus being 'timeout' and the errorThrown being an empty string. I've also tried increasing the timeout to 60 seconds, but that doesn't seem to help either. In addition, I verified that the server is returning the correct response headers, including `Content-Type: application/json`. I've looked into potential issues with JSON parsing or response size limits on the server side, but everything seems fine there as well. Is there something specific I need to consider when working with large responses and high-latency environments? Any suggestions on how to handle this better or alternative strategies to retrieve the data successfully? I'm working on a CLI tool that needs to handle this. Is there a better approach? Has anyone dealt with something similar? I've been using Javascript for about a year now. Cheers for any assistance!
