Hi, Yesterday I learn many thing from you, especially from Marc and my problem was solved ( session variables lost between pages or use same variables ). But now I continue asking: I don't want to use Session ID(session.use_trans_sid = 1) between pages. But also I don't want to use same session variables for different users at same application and also I don't want lost session variables between pages for same user. Is it possible? If yes how? Thanks for everybody for any help. Best regards. I have Wamp Server(2.2.11) with PHP(5.2.9.-2). My php.ini's session settings at below: [Session] session.save_handler = files session.save_path = "c:/wamp/tmp" session.use_cookies = 0 ;session.cookie_secure = ;session.name = PHPSESSID session.auto_start = 0 session.cookie_lifetime = 0 session.cookie_path = / session.cookie_domain = session.cookie_httponly = session.serialize_handler = php session.gc_probability = 1 session.gc_divisor = 1000 session.gc_maxlifetime = 1440 session.bug_compat_42 = 0 session.bug_compat_warn = 1 session.referer_check = session.entropy_length = 0 session.entropy_file = ;session.entropy_length = 16 ;session.entropy_file = /dev/urandom session.cache_limiter = nocache session.cache_expire = 180 session.use_trans_sid = 1 session.hash_function = 0 session.hash_bits_per_character = 5 url_rewriter.tags = "a=href,area=href,frame=src,input=src,form=fakeentry"
