I am currently developing a site, and I need to integrate some XML market

  • 0

I am currently developing a site, and I need to integrate some XML market data a third party is providing. They sent me lots of documents about how to make requests for different types of information, and also how to make a login request. However, my research tells me you cannot use XMLHttpRequest to access data from remote servers unless you are running a proxy, and then the proxy can make the request for you. Also, my understanding is that the third party’s logins expire every 24 hours. Can I then have my theoretical proxy automatically renew the login request every day? Sorry if my questions sound dumb — I am so very new to XML and any help would be appreciated!

Cheers,
Jane

    Your research is correct. You cannot directly make cross domain requests with XMLHttpRequest. Using a proxy is one solution. Another is to ask the 3rd party to implement JSONP: http://en.wikipedia.org/wiki/JSONP
