Note that PHP session cookies don t use httponly by default   To do that    sess name   session name    if  session start          setcookie  sess name  session id    null       null  null  true       A couple of items of note here    You have to call session name   before session start    This also sets the default path to      which is necessary for Opera but which PHP session cookies don t do by default either

Be aware that HttpOnly doesn t stop cross-site scripting  instead  it neutralizes one possible attack  and currently does that only on IE  FireFox exposes HttpOnly cookies in XmlHttpRequest  and Safari doesn t honor it at all   By all means  turn HttpOnly on  but don t drop even an hour of output filtering and fuzz testing in trade for it
