Today I wrote a servlet to be accessed via WAP from mobile phone. While perfoming a request, this servlet adds a cookie to response with some important information. But after testing, I found out that all my cookies were stored in SIM card (I replaced several phones, and cookies, that comes with request to servlet were wxactly the same). After setting 20th cookie, i was unable to set any more.
Old cookies weren't replaced by new ones
So, have another question to ask.
If cookies are stored in WAP-Gateway (or something like that) how can i identify client's phone (not a client). Because problem is: when i use various phones with one SIM card, all cookies remain the same.
