+## Can I specify different PDF in the default viewer?
+You can modify DEFAULT_URL variable in the web/viewer.js file. Or, you can append the `?file=` query string to the viewer URL, e.g. `http://mozilla.github.com/pdf.js/web/viewer.html?file=compressed.tracemonkey-pldi-09.pdf`.

-## 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, which means it cannot do cross origin requests (see [Same origin policy](http://en.wikipedia.org/wiki/Same_origin_policy) and [example](https://gist.github.com/3452072)).  There are some possible ways to get around this such as using [CORS](http://enable-cors.org/) or setting up a proxy on your server that will feed pdf.js the pdf.  Both workarounds are out of the scope of the pdf.js project and we will not provide code to do either.
