I have a WebForms application running on IIS at port 80.
I have a PayPal button on the Checkout.aspx page. This button uses javascript to call the CreateOrder function in the same machine server-side javascript Node.js app running on port 8888.
The problem is that the client javascript is not able to communicate with the nodejs server.
I’ve searched the web and all I found is create a IIS Reverse Proxy mechanism. But that’s for the entire site, so any user request on my site will be routed to Nodejs; and that’s not what I want. I only want that button to call Nodejs. So how do I make that happen? Much appreciate any suggestion.
