Progressive loading not working while loading pdf from another domain.

[kishanj918]

When i load pdf within my domain, progressive loading is working. But when i load pdf from another domain i am getting Refused to get unsafe header "Accept-Ranges" error.

This sounds like a CORS issue, please see https://github.com/mozilla/pdf.js/wiki/Frequently-Asked-Questions#faq-xhr. Closing as answered.

                add_header 'Access-Control-Allow-Origin' 'https://www.docstub.com';
                add_header 'Access-Control-Allow-Methods' 'GET';
                add_header 'Accept-Ranges' 'bytes';
                add_header 'Access-Control-Allow-Credentials' 'true';
                add_header 'Access-Control-Allow-Headers' 'Range';

Is there any solution yet?
I'm loading PDF from different domain. It is loading the PDF fine but not in chunks. It loads full PDF at one go.

It loads full pdf instead of loading chunk by chunk when do cors request

@pravid see #3150 , I solved this by add ExposedHeaders

@zsybupt Thanks for informing. I tried adding expose header to my file but it is not working. I'm using rackspace cloud. Below are the headers I have set,

Content-Type: application/pdf
Access-Control-Allow-Credentials: true
Access-Control-Expose-Headers: Accept-Ranges, Content-Encoding, Content-Length, Content-Range
Access-Control-Allow-Methods: POST, GET, OPTIONS
Access-Control-Allow-Origin: *

What do I'm missing?
