Telephone does not apply to session cookies

Question

Using Phonegap-3.0.0 + ios6.1 , on a real iphone, in a real https domain processing a server, many answers from different sources lead me to many trials and failures with session cookies, I still can’t process them correct on the Iphone5+Phonegap app , although everything works fine in Iphone5+Safari .

Sources of Information and Understanding

• Cookies-in-PhoneGap . This involves using a different transport mechanism to exchange cookies between clients and the server. Process the cookies on the wire (javascript set:document.cookie=... and get:xhr.getResponseHeader('Set-Cookie') ) and save it in Phonegap-html5-LocalStorage to receive it and reset in the next ajax request.

• Iphone and Phonegap . I found this cocoa code in the app>Classes>AppDelegate.m . I don’t think I need to modify it. It seems to be activated by default. My php server is still telling me Your session has timed out, or you have disabled cookies. .

I have been working with this client server for several months in different contexts, I always worked until the phone book appeared in the picture.

Questions

• From web readings, telephone delay should be configured to support cookies. Right or wrong?
• Does Phonegap really handle cookies by default (like when creating a project)?
• Should a developer implement a cookie transport mechanism?

Thanks in advance.
