What is the best way to retrieve an AJAX response from a different domain?

Are there alternative methods to retrieve AJAX response and access data from a different domain without requiring changes on the server-side code?

While YQL offers this feature, it comes with limitations such as a maximum of 1000 calls per hour for free users, though many users have reported experiencing lower limits.

Answer №1

If by "without altering server-side code" you mean not changing the server hosting the data source, one option is to set up your own proxy server (essentially creating your own YQL server) to fetch the remote data. This workaround is feasible because server-side operations are not restricted by the Same-Origin Policy.

You can make an AJAX request to your server, which can then retrieve data from the remote server using tools like wget, curl, or fopen, and send back the fetched information:

Remote server <- fopen, curl or wget -> your server <- AJAX -> browser

Answer №2

Utilizing HTML 5's postMessage feature allows for cross domain calls, although it may not be compatible with all browsers. For more information on how to implement this, visit the link provided: Cross domain communication through postMessage

Answer №3

If you're looking for a way to make cross-domain calls without using JSONP, consider implementing the iframe receiver pattern. This technique, although old, can still be effective. For more information, check out Danny Thorpe's article on MSDN titled Secure Cross-Domain Communication in the Browser.
