Question External Subdomain to a plesk folder

[sl3computer]

Hi

I have domain1.com and domain2.com which are on separate webspace servers. In both the downloads folders (/downloads) they have same contents for website users to download documents, media, etc.

Now users currently use domain1.com/downloads/ and domain2.com/downloads/ for items that they require. I can create a subdomain for domain1.com like dl.domain1.com

Is there a way like dl.domain1.com/item1.pdf to be downloading from domain2.com/downloads/item1.pdf, Please let me know how its possible using plesk. Basically I want just one same-domain link to download from the other webspace and still host both sites on separate servers,
