## Can I load a PDF from another server (cross domain request)?
Not by default, but it is possible. PDF.js runs with the same permissions as any other JavaScript code, which means it cannot do cross origin requests (see [Same origin policy](http://en.wikipedia.org/wiki/Same_origin_policy) and [an example](https://gist.github.com/3452072)). There are some possible ways to get around this such as using [CORS](http://enable-cors.org/) (see also [unsafe headers issue](https://github.com/mozilla/pdf.js/issues/3150#issuecomment-17582371) and [Access-Control-Expose-Headers issue](https://github.com/mozilla/pdf.js/issues/4530)) or setting up a proxy on your server that will feed PDF.js the PDF file (example: https://github.com/mozilla/pdf.js/issues/1000#issuecomment-133756244).

Please notice that generic/demo viewer blocks this functionality if deployed not on mozilla.github.io domain to avoid content spoofing (see https://github.com/mozilla/pdf.js/pull/6916).
