We are doing a hybrid app with Phonegap and jQuery Mobile that, through ajax requests, retrieves some data from an external server in JSON format and then treats them.
We have never had any problems in iOS or Android. Since we updated the security certificate of the domain (we force the signature algorithm to be SHA-256 with RSA encryption) to which the App makes the requests, the Ajax connections return a 404 error , when the day before being still the certificate with signature SHA1 there was no problem. In iOS on the contrary still does not give us any problem.
Could someone give me some light about it?
