Description N 2018-06-14 01:02:20 PDT 
I've been using the same code for years and things have been working very well on every browser so far:

$.ajax({
    url: '/test.php',
    data: parameters,
    dataType: 'html',
    type: 'post'
})

However, since my users started to upgrade to iOS 11.4, those who use the Private mode of Safari are having an issue with "being disconnected" from my website.

This is because ajax POST requests aren't sending any Cookies, apparently. A whole new session is created as part of that POST request (new cookies created, etc).

However, that doesn't affect anything on the GET requests themselves. They stay with the same cookies (and therefore same session), even though new cookies were set as part of the ajax POST request. It's like those ajax POST requests are "sandboxed", not affecting anything else.

Any ideas? Is this a bug on Safari on iOS 11.4 ?

It somehow seems to send consistently DIFFERENT cookies.

They are related to my website, e.g. same Session Cookie name, but with a completely different Session ID in the value.

It doesn't send other cookies that would normally be sent in that POST request, though... (but on Normal (non-Private) mode they are sent, correctly)

Are you using service workers? We had a regression in iOS 11.4 related to service workers, cookies and private session. The bug was fixed recently but has not shipped yet.

If service workers are involved, this is very likely a dupe of Bug 186205.

I use service workers, yes. When will this be shipped?
Comment 6 Chris Dumez 2018-06-14 11:56:10 PDT 
Unfortunately, Apple does not comment about when a particular fix will ship to customers. I cannot say anything until it ships in a beta.

If you have a test page, I'd be happy to confirm my fix works for that test page as well.

(also, the fix will presumably be in the next Safari Tech Preview to verify)

The bug was reported on iOS...

I still see that this issue is happening for all Safari browsers and it is not consistent, i.e. it send with most of GET requests but not all.

In two of our apps, we see that the request was not being sent with cookies at all for variety of requests including GET and POST.

Please fix this as it is very annoying and hard to detect.
