Session don't store after header("Location: ...")

Hi everybody, I have a problem with mysql session handler and redirect. My situation: - mysql session handler - one page is "posted" to another page, that saves a session variable and redirect to the first page again. If I do the redirect the variable is not properly setted, otherwise it's all ok. My PHP version is 4.3.10-16 They said me I have to use cookies, but I use this. I use this code before starting session: @ini_set('session.use_cookies', true); @ini_set('session.use_only_cookies', false); @ini_set('url_rewriter.tags', ''); @ini_set('arg_separator.output', '&'); Can you help me? bye and thanks in advance -- Giacomo
