php - Cannot save cookies or use a db, need to display a message only once -


i'm developing pre built php based system.

for restrains cannot explain, cannot use cookies, sessions or db link.

i need display message once every visitor comes in.

any creative ideas guys can think of?

thanks,

here ideas

  1. use browser's localstorage
  2. pass message using post or on querystring. not safe option
  3. use flash store. same #1 don't need flash!
  4. use file disk need able remember owns file since multiple people on same server. without using cookies, not sure how this.

i using localstorage. first page create javascript stores message on browser's storage , second request pull message , display it.
