I just came here to say thank you so much for sharing and explaining the knowledge that you have, you explain with so much patient and passion that I was able to understand completely. Keep up the good work.

Thanks a lot Telusko Learnings for helping me to upload this wonderful and very helpful video....really sir your all video is awesome on java and jsp-servlet.....we hope next time we will get more videos...thanks once again...

You saved my life!!!! Greetings from Colombia!!!

[@rajmehta651]

Wow,what a useful video ❤

[@omer_usta]

Never use Expires = 0 to prevent caching. The Expires header is sent by the remote server and passed through to the browser by the Portal Server. Unless the time on all three machines is synchronized, an Expires=0 header can mistakenly return cached content. To solve this problem, set the Expires header to a fixed date that is definitely in the past.

[@ruiyijohnwu6295]

The disable back button really makes me laugh. I really appreciate you made such wonderful videos.

[@joeljacob1066]

Both the videos really helped me a lot. Can use tell how to prevent the same user accessing different browser at a time

[@milaanvigraham8664]

Whenever you make changes in jsp files, you must refresh the project. You don't need to restart the server. Nor do you need to clean the project. Thanks for the video though :)

[@jayantagarwal6339]

Awesome Sir, this what I wanted to learn

[@webdev4786]

great....this woes the only problem am facing after i have done a complete functioning website

[@hikmatmarashdeh2293]

Thank you very much for your amazing explanation and demo.

[@nitishrohilla5822]

Thank you sir for this video by the way i already found this method on stack overflow after a long wait..😅😅 and you are right disabling back button is not good method user will feel annoyed .but your way of teaching is very funny..😂😂😂. And one more think i wanna tell you please disable cached in browser>console>network when you are testing your site on browser. it will help you and you will never face that html editied effect issue in your webpage.

[@mesimple100]

Not working, i m still able to go back to previous pages

[@kiranparui4637]

Thank you so much sir...i was waiting for you to make this video....

[@anandsharma8535]

Sir when we click on the back button after logging out it says to resubmit the data or reload the page and when i clicked on reload button we were back on the index page. What can we do prevent that?

[@user-a2-23]

exactly .I just came to comment the same . @telusko please tell this concept

[@sagarmeena0210]

thanks for making these video...they're really helpful

[@erdeepakkumar61]

Sir after logging out I can still go to welcome.jsp page by pressing back button. I had set the headers to stop the caching but still the problem is there.

[@chauhanraj659]

This info of postback I was searching from a long time! This video gave the concept of response.setHeader(..) !!!

[@gouthamboine1898]

hello sir, setHeader method working only once. if i click my back button more than one time its showing me the secured pages again. please help me out.

[@irfanansari6448]

Thank you so much, it really helped me in my project.

[@CodeWithCB]

The solution you mentioned is browser specific. So how to generalize it so that any browser back button click will fail for secured resource access, after logout?

[@waytolearningcomputerscien6558]

sr your videos are very useful ,please upload some video related to jsf in java

[@syed12385]

Sir, I used complete code it’s working .. But after login if we press back button it shows login page actually it should not ...plz check

[@divyanshchaudhary7063]

Even In my code it's showing Click resubmission and after click back again it reload to the login page.

[@akshaysatija7505]

I have done the same thing but after logout i can go to my previous page ?

[@modernsanskari4398]

There is still a problem with Login module. After entering the correct username and password ,you will be redirected to welcome page. But if you press Back button it wil again show the Login page i.e you are logged out without clicking on logout button. Can we make exact login module like FB,Gmail etc . Also how can we disable back button and we can easily give a navigable button on the web page only.

[@prasannareddyisireddy8233]

Have you find the solution??

[@AbhishekKumar-zg7if]

Thank you. Important information.

[@romilsondgerard1978]

Thanks for such a great video! Thing is, when we do no-cache, I can no longer travel between pages once the user is logged in. So how can I prevent back button after logout but still be able to travel between pages while logged-in?

[@giorgiogaratti6652]

Thanks! Very useful...

[@arpandutta3106]

what if i want the pages to be cached for faster access, but it should only be accessed if we are logged in.

[@anujaashokjaiswal5578]

thank you so much you save my life

[@milaanvigraham8664]

I have a question. This method seems to depend on a client's browser to be secure. What would happen if someone releases a browser that ignores this particular header? That chooses to store the cache data anyway? Isn't that perfectly possible?

[@madhumitanaskar962]

Hi Sir, I have written the below code in my JSP file to prevent the back button to work. But it seems the code is not working: response.setHeader("Cache-Control", "no-cache, no-store, must-revalidate"); response.setHeader("Pragma", "no-cache"); response.setHeader("Expires", "0");

It is not working for me aswell, did you find a solution yet?

there is that trick where you use "inspect element" and then you change the tag of password type="password" into type="string" and so see the password. Is there a way to avoid this?

[@abdulmominkhattak]

I don't think there is any solution to that.

[@soumyadeepganguly5892]

Shouldn't we disable the new sessions created with jsp with page session=false directive? Cause we only want the one session created after login and attach the user to the session attribute. right? We don't need all those jsp sessions

Thanks alot sir 😊😊

[@kiran7087]

After clicking back button,it is showing "document expired" error but i wanna login page there also,what i have to do sir please give me suggestion

[@princedey6536]

Sir, is there a way to achieve this by using RequestDispatcher instead of SendRedirect? Because the page that i send the user displays some data that i have set by using request.setAttribute() hence need to forward request and response. With requestdispatcher upon hitting back page gives cache miss error. Upon reloading the same page reappears.

Thanks for the solution, but here is one more problem that when we back button more than one time and refresh the page, the browser is asking for resubmission, if we click continue then it is displaying that welcome page again.

Please make a video on database connectivity as soon as possible Atleast try to make it first rather than form validation using JavaScript

[@vinodluhar4505]

javascript is not so effective. If client side uncheck "allow javascript", all validations will be fail.

[@priteshshinde6779]

Not like that

[@priteshshinde6779]

I know client side validation is important But it is not mandatory But database connectivity is most important part as well as it is a part of JSP or Servlet code But validation is done by JavaScript which is totally different language
