WebGL cross-domain error when loading .mem file from remote

Hello,

I am trying to host the WebGL build files (.mem, .data and .js) in another server from my game's website and there is a problem with the browser's Cross-Domain restrictions.

I CAN load scripts from another server, because it is using Access-Control-Allow-Origin with '*' on the remote server. When I used Webgl prior to version 5.3, there was no problem, and I don't know why, since it also used XMLHttpRequest.

Error:

XMLHttpRequest cannot load http://remoteServerName.com/webgl/Release/webgl.mem. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://originServerName.com' is therefore not allowed access. The response had HTTP status code 404.

Line of code of UnityLoader.js that makes the XMLHttpRequest to load and decompress the "webgl.mem" file:

 function DecompressAndLoadFile(e,t,n){e+="gz";var o=new XMLHttpRequest;o.open("GET",e,!0)

Tha strange thing is that on later versions, when the loader was named fileloader.js and it didn't have the DecompressAndLoadFile function, it was working fine and I could load all the files from remote server without any problem.

My question is: how can I modify the above code so that it will load the .mem file with success?

IMPORTANT: I can't to host the .mem file at the same server, because of technical restrictions.

Thank you in advance.
