强制重复资源文件请求以发出单独的HTTP请求?

I realize this is generally a bad idea, but I want each duplicate file resource link on a site to make a separate HTTP request.

Let's say there's some imgs that requests a file, like so:

<img src="http://example.com">
<img src="http://example.com">
<img src="http://example.com">

Typically, the browser would make only one request for http://example.com, which is great for performance and makes a lot of sense!

I'd like the browser to make 3 individual requests, each and every time http://example.com shows up.

By the way, the page I'm linking to is a PHP redirect file, so maybe that opens up some possibilities? It'd be great, if I could just add some headers to the PHP file, but I don't know if that's feasible (just started with PHP so I'm admittedly naive).

Any info at all is welcome, thank you in advance!

This is 3 separated requests.

<img src="http://example.com?t=1234">
<img src="http://example.com?t=2324">
<img src="http://example.com?t=4355545">

For generate string random: (in PHP)

<img src="http://example.com/img.jpg?t=<?=uniqid()?>">

And browser is not cached your image
