i have been having problems cors in app. using futurepress' epub.js library load , display epub files.
epub.js straightforward , works passing url epub resource want render. example:
var book = epub('http://www.feedbooks.com/book/88.epub');
the problem have receive error regarding cors says "xmlhttprequest cannot load [url]. no 'access-control-allow-origin' header present on requested resource. origin 'null' therefore not allowed access.
i not sure how can add proper cors headers request when being made within library itself. there way can intercept request , add then? when use chrome plugin "allow-control-allow-origin: *" works well. i'm not sure how plugin manages fix problem though.
this app client-side app built in angular. thanks.
