[@arun1993apr]

i'm gettting only o/p as sq called........but not displaying result is 25......how to solve

[@mjrocks4603]

Hi Navin, In Sq servlet you have initialized int k=0; but why it's not taking that value.

[@sumit_singh684]

What is the necessity of using cookie when we have session

[@waqash13]

Sessions are maintained server-side whereas cookies are stored on the browser.

[@preeti3911]

Session also helps to keep track of visited states

[@mukteshgautam4050]

one task of cookies is to maintain a login in session we set a cookie in browser(using seerver side) then we want that cookie(demand the cookie from the browser) in server side again to authenticate if the session is maintained so cookies are send from client to server again and again to keep logged in this is called authentication via cookies!

[@chinmaydas4053]

These are the great topics..eagerly waiting for more videos sir 🙏..

[@haiqiangzha3363]

A question here, since you mentioned previously that the client will only send cookies to the serve with specific domain name, why will it send the cookies obtained from AddServlet to sqServlet? I mean, I think the client will not send cookies obtained from AddServlet to any other servlet. Could any one explain?

[@pooraniv4941]

sir can u help me..I want to make payment integration in my project...would u tell me the way to do in jsp+servlet

[@kamltriaza4091]

can we have res.addCookie and req.cookies in the same servlet ? pls answer me

[@bhavaniyallavula2575]

Sir, why Session management and Http session cookie doesn't work on doPost method? It is reasonable that url pattern doesn't work on doPost method but I can't understand what's the reason for the other 2 ways not working? Please give clarity on that.

[@javawithumesh7707]

Please explain cookies and http session in detail once again

[@sachinsingh-vm1fc]

Why we use sendredirect method when we are using session based servlet to servlet technique ??

[@miracleweddingslive4458]

thank you for making this vedio!

[@ggeilokowski]

Does the Client send the all the cookies or only the cookies corresponding to the webside? I know this is a dumb question but i just want to clarify.

[@shrikarsharma2553]

how can we create object for HttpSession, ReuestDispatcher or SendRedirect as we cannot create objects for interfaces. pls clarify...

[@sanukumar4845]

If the request object remains the same across pages why can't we set attributes in it and retrieve it in the redirected page? Is it because the redirection is a new request? If so is it possible to save the current request object and send it to the redirected page on redirection call?

[@pratikgupta7373]

Thanks for uploading

[@ChetanRawattunein]

I have a website as frontend having a login form and spring boot as my backend doing validation, I want to maintain a session after validation with rest API but it's not working. It creates a new season for the next page Any suggestions ?

[@techcollege3762]

in Session or send redirect can i use post method

[@arhamnaik3087]

U ought keep fonts a bit bigger ... However sir your videos are really helpful..thanks a lot for that ..

[@jiteshsharma4692]

Superb.....good. navin. Sir

[@piyushtakale4648]

how you are using servlet classes and methods without importing. im new in jsp/servlet world i need to know this

[@karthik.b8512]

What's the difference between session and servlet context and when to use what?

[@charan_75]

Did you find out?

[@annapoorania8860]

i got this error: Type mismatch: cannot convert from javax.servlet.http.Cookie[] to org.apache.tomcat.util.http.parser.Cookie[] i dont get what i did wrong :( in sq class

[@RezaJafari1984]

So Session does not work without sendRedirect . Am I right ??

[@sagarmeena0210]

amazing tutorial

[@gulamnabikagathala3762]

Under the Cookie Object (or after it )add this line what does it do ,Makes it *public* to any Servlet can acces it Cookie_object_name.setPath("/"); Thank me later :D

[@turab_0]

Sir , do we need to learn servlet&jsp in2018?

[@MohammadSalibi]

14 dislikes !! ... he is just a crazy who will give such a nice teacher and wonderful lesson a dislike

[@wpatyune1631]

Is RequestDispatcher not commonly use if we have sendRedirect to do the same job? Otherwise, what occassion to use it? Thanks.

[@mukteshgautam4050]

Both seems like to do same job in the example but RequestDispatcher is *sending the initial request* made by the client to other "second" servlet (using the first servlet) whereas the sendRedirect(sends response) is *sending the response by using url specified in sendRedirect* it could be any url and in the example it was the url for the second servlet and when this url hits the browser it goes to tomcat and then to second servlet for which the url belongs as stated in the sendredirect("/sq");

[@javascriptwar9525]

[@beticogerenense]

Eres un fiera.

[@kabilr1820]

The name of the second servlet is sqservlet am I right? But you just write sq in requestdispatcher. Why?

[@sailakshmiv4101]

Sq is a path not servlet name.. We mention mapping details in web.xml..

[@prof_as]

thats the url of SqServlet by which it is accessed

[@manjushasinha702]

How can I maintain two data in a single session?

[@pramodaryal1788]

String s1=req.getParameter("num1"); int a=Integer.parseInt(s1) ; int b=Integer.parseInt(req.getParameter("num2")); int sum=a+b; res.sendRedirect("sq?a="+a+"&&b="+b); //URL Rewritting

[@pramodaryal1788]

Cookie cookie1=new Cookie("a", a+""); res.addCookie(cookie1); Cookie cookie2=new Cookie("b", b+""); res.addCookie(cookie2);

[@appsytech3000]

use array bro

[@vijik2988]

Please do the theory so that we can understand exact what it is please

[@sarvodaykumar2723]

If 2nd servlet is in different server how the session will available there

[@mukteshgautam4050]

Session is per session in the browser when you visit a website and not differ for servlet to servlet in backend like you using youtube. session is global if you know what i mean.

[@prof_as]

can't we use HttpSession in doPost()

[@bikasgupta4454]

Thank You sir

[@preethamm.n1161]

Sir upload theory vedio on cookies Please sir🌹

[@bhabanadas1747]

how to print session data in jsp

[@deeproy7292]

flowing of cookies from one servlet to other please

[@saurabhwaghmare393]

your work appreciated....nice explanation. I have one doubt, anyways we have forward(req,resp) using which we can transfer data from one servlet to another servlet then why there is a concept of the session?

[@saurabhwaghmare393]

I got that.... Forward, including redirect these all are used to move over servlet. Session is used to send the data over servlets/pages

[@swapnilankushe2905]

Thanks Sir..!

[@Prapti.p]

@@ishaangupta6572 bucks is a slang for dollar, pound, rupee etc.

[@manindersingh6371]

you are teaching too much fast. Instead of explaining the things you are just practicing yourself. If someone is beginner then this tutorial is not for you. I have watched so many videos and I really like the way of your teaching but this tutorial I don't like it.
