Francis, That was it! The subsequent, asynchronous AJAX call was responding with a Javascript redirect that was remedied using Nginx's sub_filter directive.
location / { resolver 103.86.99.100; proxy_bind $server_addr; proxy_pass https://$host$request_uri; proxy_redirect https:// http://; proxy_set_header Accept-Encoding ""; # Needed by sub_filter to disable gzip compression sub_filter_types text/javascript text/css text/xml; sub_filter 'https:' 'http:'; sub_filter_once off; } The combination of disabling gzip compression, adding sub_filter_types text/javascript, and creating sub_filter 'https:' 'http:' rewrote the protocol of the Javascript redirect. {"url":"http:\/\/z1.fm\/download\/3298838","isSuccess":1} Then, I was able to download MP3's by simply clicking the AJAX link. Hope this helps someone in the future.
