Ask HN: How to proxy per file extension in Chrome?

Let's say, we've 2 HTTP/HTTPs proxies a) 127.0.0.1:8080 b) 127.0.0.1:9090

Now, we want:

1. All the URLs having .html extension to go through this proxy a) 127.0.0.1:8080 2. All the URLs having {.png, .jpeg, .jpg, .pdf} to go through this proxy b) 127.0.0.1:9090

Can anyone tell me how this can be achieved?
