In place refresh, back button

I am wondering if any one has tried to fix the "back button" issue when they use the inplace refresh option with a portlet. For those that dont know, when you are on say the third page of an application and you hit the back button, the user would expect it to go to the second page. Instead it goes to the page before you started clicking on the portlet. Let me know your thoughts everyone.

We are facing the same issue, will appreciate any ideas on possible solutions.
Thanks,
Laura

Terminate User Session

Hi all,
I'm using FM TH_DELETE_USER to delete a user session, however this will terminate all sessions. Can anyone suggest a system function that will delete a specific user session?
Thanks, Mark

Hi ,
TH_DELETE_USER kills the sessions of the user.But there is no FM to delete the particular session.
But if you Debug SM50 you get some info.
i tried it i got this...
CALL 'ThWpInfo' ID 'OPCODE' FIELD OPCODE_WP_DEL
ID 'WP_INDEX' FIELD WP_TABL_ALV-WP_INDEX.
in this program <b>RSMON000_ALV</b> you can find the code .

Terminate user session api

I need to write an app that allows a person to identify a user session and terminate it. Also, access manager may be clustered, so I'll need a way to access each machine name to check for sessions.
Could someone point the way to which api methods I should check out?
Thx.

I know AM can do it... but the users won't have direct access to AM... that's why I need to figure out if any of the library API's allow access to that feature.

Invalidate session when user clicks back button

I want to invalidate the session when user clicks back button, so that user cannot refresh and reload a page.
Any suggestions will be highly appreciated.

}The problem with even attempting to do this is that with today's browser capabilities, users can optionally choose to jump to a particular page in the browser history and this may not necessarily be the most recent page. In this case, you would also want to invalidate the user's session after already having been there (whatever page that may be). Then you have situations when the user may wish to jump back in history to external pages they were visiting before they reached your own site's pages. Then what happens when they start clicking forward, forward, etc... from there? This is why I prefer writing Swing Clients as alternatives to browser applications. There are soo many possible ways break web applications made for standard web browsers both maliciously and simply by accident or irregular user patterns. Regardless, this servlet would work based on the assumption that all the user(s) would "ever" do aside from moving logically forward is clicking on the browser's "back" button.

How to get login page when user clicks on browser's back button

Hi,
I am using struts framework.
I have set property nochache=true in response header of all pages.
So, browser does not caches my pages.
Now,when I am clicking on browser's back button, I am getting following message..generated by browser.
Warning: Page has Expired The page you requested was created using information you submitted in a form. This page is no longer available. As a security precaution, Internet Explorer does not automatically resubmit your information for you.
To resubmit your information and view this Web page, click the Refresh button.
Instead of that I want to show user a login page, when it clicks on back button.
Can anyone help me?

Hi,
I agree with your suggestion.But my query is,
If you have seen many credit card or banking websites,generally when user clicks on browser's back button,its redirectly user to login page of it for security reasons.
I want to implement that kind of functionality.So need help on that point

TS 4.1 User Interface Forward/Back Buttons

I'd like to the add the Forward/Back Buttons to my User Interface similar to those in the Sequence Editor. I use a modified version of the Full Featured UI on the production floor and often switch to editor mode to work on the sequence. I find it very cumbersome not to be able to jump back and forth between Sequences while doing so.
Were the buttons created using the "Editing Class" proporties and methods to build a stack of recently selected sequences? Or are the buttons already existing with the methods simply needed to be called?
Any suggestions how to impment this functionality while in edit mode?
Thanks

"but keep in mind that the UI is not meant for developing. It instead was designed with operators debugging in mind."
I don't agree with that. The UIs are fine for developing if they meets your needs. If not, then you have to weigh using the sequence editor, which is not nearly as customizable, vs the cost of reimplementing whatever you can't do without that the sequence editor already has.
Note that most of the things that are missing from the UIs would take a fair amount of effort to re-implement (type editing, ...). If there were already simple-user-ready-drop-in-components for the missing features, we probably would have already included them in the UIs.
We want the UIs to be functional, but the top priority is that they be simple enough such that they can be readily modified.
Note that in some cases there are apis to support features that aren't in the UIs, but there isn't a complete control that wraps everything. For example, Engine.SearchFiles() is a huge amount of the implementation for find-and-replace, but there currently isn't a user callable dialog for invoking it or a user accessible control for automatically browsing the results, thus we don't currently include that feature in example code for the UIs. I don't know the specifics of forward/back, so I'm not sure how much of the implementation is exposed as public APIs, beyond the goto-location functionality (see Locations.GotoLocation, ...).

Back button of browser

hi,
i have built an application and want to disable back button for the user. how can i do it
Thnx,

You can't doing it using Java.
You can override the history.back event with history.forward in JavaScript (which has nothing to do with Java) or you can simply not show the nav bar. Which doesn't mean the user couldn't use the backspace key instead...
Short:
- you're wrong here
- you can't

Branching and Using the 'Back' button

I have created a branching program that is essentially a
"choose-your-own-adventure." There is no quiz, b/c there is no
right or wrong.
However, when you begin you have three choices. The user
selects one of those choices and goes to Slide A, Slide B or Slide
C depending on their choice. There, they have more choices to make.
From Slide A, their choices would take them to Slide D, Slide E or
Slide F. If they originally chose Slide B, the next set of choices
would also be Slide D, as well as Slide G or Slide H.
(And so on and so forth)
It has been recommended to me that I create a way for users
to simply hit the playbar's "back" button if a user is on Slide D,
and wants to go back to Slide A. However, under my current set-up,
I have two problems: The first: if they simply hit the back button
on the slidebar from Slide D, they will go to Slide C--a
acompletely wrong choice. Secondly, if I put a "Jump to" button on
the page, I actually have to put 2 on (one that will bring them to
Slide A and another that will bring them to Slide B) since you can
get to Slide D from both A and B.
This is a simplified version of my branching, and creating a
button for each page that a slide could go back to isn't feasible
and would probably be more confusing to the user than anything.
Please tell me if this doesn't make sense, or if there is a
way that I can do this.
To see the project and see what I'm talking about, you can go
Here,
and then choose the "Is My TV Ready?" option.
Thank you,
Rob

Hi Rob
Had a look at your program and think it is a great use of
Captivate.
Regarding the "back" functionality, I would recommend to
custom build a button on each slide where you wish to go back. The
reason is that the back button on the play bar will always go back
1 slide in the actual slide sequence and does not take branching
into account i.e. it is a pure linear back 1 button. To make life
easier, I would suggest giving each of your important slides a
unique label, which would then make it a lot easier to:
Specify where the individual "back" buttons would jump to
View the actual branching in teh Branching view of Captivate.
Good luck mate

Urgent ...problem with back button in my browser

hello,
i created one login.jsp file and wellcome.jsp file and one logout.jsp file and one login controleservlet.If i login once i got wellcome page.In that i have logout button, and if i will click that button
it will display logout successfully message on browser.my requirement is that after i will get logoutsuccessfully message i want to avoid back button in my browser.if i click back button then it will display an error message like "your session expire".
please send the reply as soon as possible.

I'm not certain of whether you want to disable the back button in the user's browser or you want to avoid this error message...
Assuming you want to avoid the error message entirely, I would set a variable in the session scope when the user logs in and any time you don't see that when you process a request in your servlet, redirect the user to the login page.
If you're looking to simply disable the back button in the browser, beyond asking the user nicely not to click the back button, good luck to ya. :)
Hope this helps!

Disable explorer back button (using JS)

please tell me how to disable explorer back button, i have made a project and i want to disable explorer back button on signout button, tell me the code using java script

The page that the browser goes back to would have to identify that it came from some place that was not right and redirect to an error page. This means you need all kinds of checking in every page. Of course, if a page has specific input requirements, it makes it easier, but you need a lot of state validation to keep track of these things. If back goes to a form submission page that already was submitted, you need to be able to track this and deny resubmission... But the browser will really be sending the same data from the original form. So you might have a hidden field with some unique ID that once used, can't be used again.
In my current project, we have a check on all pages to redirect to login. Login uses Javascript to popup the actual login and application in a new window without menus and toolbars. This removes the back button. The user can still use the popup right-click menu to go back, but this is not a common thing for many users, and we have our pages designed in such a way as to facilitate going back when appropriate, but when not, they can't.
In some ways, you have to trust that the user isn't going to go back when it's not appropriate... well, I might be dreaming here...

Firefox was a good, but now it's slow and when I search google I have to refresh the page when I click the back button. This is driving me to other browsers.

When searching in goole, If I click on a link and want to go back a page firefox does not load the previous google search without refreshing the page. Because I use google frequently this is very annoying. Firefox has also been freezing and crashing most frequently of any of the other browsers that I have been driven to use. I'm not sure why I should keep it on my computer at this point.

Regarding the Google results page blanking out when you go back, this occurs when using a combination of three settings, which may be fairly common:
* Zoom level higher than two steps (120%; the newest versions of Windows apparently default to 125%, which Firefox detects and adopts)
* Google search set to instant prediction results (default on Google search, but can be disabled in Search settings, see [https://support.google.com/websearch/answer/186610 Google Instant Search Help])
* Opening results in the same tab, then using the Back button to return to the results page (default on Google search, but can be changed in Search settings to open results in a new window/tab, see [https://support.google.com/websearch/answer/425 Google Search Help])
Firefox's cache feature attempts to maximize speed for forward and back actions by storing the last rendering of the page. Something about the instant prediction results ''with zoom'' is causing Firefox to briefly display the results and then they blank out and you have to reload the page to get them back. The mystery is why this only occurs (so far as I have heard) on Google? Is one of Google's scripts blanking out the page? Does Google care that it's messing up Firefox users?
For now, if you do not want to or cannot change any one of the three factors needed to experience this problem, you can disable the storage of the last rendering of the page. Then Firefox will skip the shortcut and lay it out fresh, which is known to work. As noted in earlier posts, you make this change using the about:config preferences editor.
(1) In a new tab, type or paste '''about:config''' in the address bar and press Enter. Click the button promising to be careful.
(2) In the search box above the list, type or paste '''sess''' and pause while the list is filtered.
(3) Double-click the '''browser.sessionhistory.max_total_viewers''' preference and change it to 0 (that's a zero).
This thread has a lengthy discussion: [https://support.mozilla.org/en-US/questions/970863 When I go back to Google search results page, it takes me to a blank Google screen].

After user logout, browsers back button is still working

when the user logout, after clicking the back button we can see the application.
Can anyone suggest me how to stop this.

which means the browser has cached your page (if IE your setting for check for newer versions of pages is probably automatically ). You need to expire your pages , if you dont want this to happen (either you have to set expiry headers in code, or you can do it on your webserver if you have a webserver fronting weblogic) or live with this behavior (you may have noticed that bank sites ask you to close your browser for added security for this purpose.
Alternately if you want to simply stop a majority of users you should change the logout to a post and perform a redirect after logout to the next page (so that back will redirect again to the same). Users would have to know to click back button twice, but this behavior is annoying

Old topic: Refresh when user click back button

Yes yes, i know, this is old topic, which already discussed thoroughly in the forum,
But, pls read my question....
i try this:
res.setHeader("Cache-Control", "no-cache");
res.setHeader("Pragma", "no-cache");
res.setDateHeader("max-age",0);
res.setDateHeader("Expires",0);
res.addHeader("Cache-Control", "no-store");
However, when i forward to a page, then click back button to the previous page, which have the code above, however, the page is still the old one, the page was not reloaded from server
Any suggestion? 1:57 am, my local time.......

I just use:
response.setHeader("Pragma","no-cache");
response.setHeader("Cache-Control","no-store");
response.setDateHeader("Expires",0);I have tried this, still the same...what can i do? Any more workable solution?
