[Solved] Icenium Ion and Caching

[Robert Sprague]

I'm sure that I'm showing my green mobile development skills, but is there a reason why Ion would be caching the result of a JSON webservice? 

I've got a pretty simple call to a webservice that just fires an alert with the result.  I updated the webservice on the remote domain to return different text.  My android device gets the new text, as well as all of the simulators, but my wife's iphone is still returning the original text.

Hi Robert,

 Are you running iOS 6 and making POST requests to your web service? Apple introduced a regression in their HTTP stack in iOS 6 where responses to POST requests are cached, even though the spec says they are to be cached only when a certain set of response headers are present.

 If you're running iOS 6 and making POST requests, could you please try to modify your web service to return the Cache-Control and Pragma headers set to 'no-cache'?
