localstorage of config works locally, but not through server

localstorage of config works locally, but not through server

I have an app that consists of three main pages. Each of the pages
communicates to a server using a URL, a user, and a password. These three
items are entered on a jquery mobile config popup from one of the three
main screens.
I was concerned about the fact that configuration from page 1 would not be
accessible from page 2, but when I ran locally using flat files, it worked
fine, so I chalked it up to that all the storage was owned by the config
dialog and went on my way.
Now, when I deploy to a server, it looks as if the config is never getting
stored, as it keeps going back and requesting the config dialog again from
the user.
I have found that if I go to the config page directly, change the values,
and save them, the values get saved just fine. The issue is when I use it
as a popup.
I am new to javascript and don't know where to go next. I guess I could
change it from being a popup to a full page and that might fix the issue,
but would like it to work as a popup for improved flow.
