How to rewrite & redirect nonsecure image urls from any subdomain through local https proxy using Url rewrite and IIS 8.5?

I am trying to redirect/redirect and pass all http-only (non-secure) image urls through a local https proxy hosted on my domain (using Url Rewrite in IIS 8.5). The source does not provide https so this is my only solution (as far as I know). Here is my code and its not working. Kindly help:

<rule name="assets redirection" stopProcessing="false">
        <match url="^(.*)\.example-differnt-domain\.com" ignoreCase="false" />
        <action type="Redirect" url="https://example.COM/p/?url={HTTP_HOST}/{R:0}" 
        appendQueryString="true" redirectType="Permanent" />
</rule>

It does not seem to be doing anything. Source images urls are in the following format

http://subdomain1.subdomain2.example-different-domain.com/xyz/abc/lmnop.jpg

There could be other image types too

I want to rewrite the url so that it looks like this: https://example.COM/p/?url=http://subdomain1.subdomain2.example-different-domain.com/xyz/abc/lmnop.jpg

Unfortunately, my regex is not really good and i am wondering I am might be doing something wrong with the pattern matching.

Any help is appreciated in this regard.

The url attribute in the match node only matches the path, not the domain. In order to match the host you will need to use the HTTP_HOST server variable. This section of the rewrite rule documentation give a good explanation of this. There are a couple of examples as well on that page that use HTTP_HOST which seems similar to what you are trying to achieve.
