Cross-Origin Request Blocked using mashup API


  I'm configuring a mashup to run from an IIS Server, instead of using the internal Qlik Sense server. Both on same machine but using different ports. IIS on 8080 and Qlik on 80.

   When I open the url http://<nydomain.com>:8080/mashupsite  the authentication is fine and the html elements are shown in the page as well but the qlik objects doens´t display.

  After reviewing the developer console I found the errror below:

  Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://<mydomain.com>/resources/autogenerated/product-info.json?1532484125189. (Reason: CORS header ‘Access-Control-Allow-Origin’ missing).

  I already added the tag Access-Control-Allow-Origin in the additional response headers parameter in the virtual proxy (default) but the error is still there.

  The server is version June/2018 and using only the default virtual proxy using ticket and windows authentication.

  Does anyone have a clue about how to solve this issue ?

Hi @KStreak , how did you solved the CORS with Salesforce?

I tried the indications from https://www.youtube.com/watch?v=slM8ZOfjOBA

The difference is that I use the Lightning Salesforce IDE and not a Visualforce page. With Visualforce page there is no CORS issue...
