caching - How to force Chrome NOT to cache redirects?

Question

A simple HTML code:

<img src="http://someaddr/image.php">

image.php is a script that returns a random Redirect to a static image with all necessary no-cache headers:

Cache-Control: no-cache, no-store, must-revalidate
Pragma: no-cache
Expires: 0
Location: http://someaddr/random_image_12345.jpg

The problem: when navigating back and forward to this HTML page, Chrome (latest win/mac) does not revalidate address http://someaddr/image.php.

I have tried using redirects 302 and also 303 (which in RFC has stronger requirement that it should NEVER been cached by browser). This works like a charm in IE, FireFox, Opera. They always refresh http://someaddr/image.php. But Chrome doesn't.

I have even used Developer Tools in Chrome, and it seems that in Network Log it even don't shows any attempt (cached or not) of fetching http://someaddr/image.php. Network Log shows only one connection already to http://someaddr/random_image_12345.jpg (cached). Why this is so broken...

I know the naive/simple solution of putting query string in image source:

    <img src="http://someaddr/image.php?refresh={any random number or timestamp}">

But I don't like/can't use hacks like that. Are there ANY other options?

Try a 307 redirect

But if you're stuck trying to get to a link that won't work due to a cached redirect...

This doesn't clear the cache but it's one quick and possible route around it if you're pulling your hair out trying to get to a link that has been redirect cached.

Copy the link address into the address bar and add some GET information to the address.

EXAMPLE If your site is http://example.com

Put a ?x=y at the end of it 
( example.com?x=y ) - the x and y could be anything you want.

If there is already a ? in the url with some info after it

( example.com?this=that&true=t ) - try to add &x=y to the end of it...

( example.com?this=that&true=t&x=y )
