I am reading HFSJ for the second time and I didn't come across this method isRequestedSessionIdFromCookie() in the book.
Please advice whether I should refer some other book also for the exam. I thought that this book would provide every detail to score 100%.
I do read the Specification but I don't concentrate on methods/details that are not there in HFSJ book, assuming they won't be asked in the exam. Please advice whether I am doing the correct thing for scoring 100%(only from the exam perspective, though I understand that scoring 100% doesn't mean that I know a to z in Servlets/JSP).
