I'm embedding an application via iframe into a someones site and need to be able to call a few of their javascript functions. Clearly running a top.cart.add() gets blocked by the same-origin policy. We've exhausted most of our options when it comes to getting them to set something up for us, so we need to try to work around them. Someone mentioned that having them set up a CNAME record could allow us to execute cross domain javascript. Is that possible? If so, how does that work. If not, how would you recommend I approach this?
Our office is set up with mostly macs (7 of them) but we do have a windows laptop and a windows desktop on the network as well. The network is configured with a modem going into a switch/router throughout the office to the computers, along with a wireless router. Everything runs fine most of the time, but periodically while using the web, certain sites will stop loading and timeout repeatedly. This usually lasts 20 minutes or so and can be incredibly annoying. Resetting the modem/router and/or rebooting the computer never helps. The weirdest part is that in almost every case, the websites are fine on our Windows machines. I frequently use github, google, Stack Overflow, and jQuery reference and I can count on the sites being unavailable to me at least once a day. While I can't get them to load, I can spin my chair around to the windows server behind me and load the sites just fine. Any idea what the hell could be going on here?
