Session ID Check when reload

I seek for a code that when the user reload the page to check if the user which the server communicate with is the same user or not to assign him some actions like visitor number or to check if the user vote in my voting before or not.

how would you know? the page would have whatever session is associated with the previous request/response. if the user reloads, the server will get that session ID. If it's still valid, it's valid... if not, a new session is created. There's no way to know that someone else physically reloaded the page.

    You get an alert about resending POST data if you go back to a page or refresh a page that was previously requested from the server by submitting form data via a (hidden) POST form.<br />
    Firefox can only make sure to get the same page by resending that POST form.<br />
    Firefox doesn't know what that form data means, so Firefox asks for confirmation before resending that form data as such an action can cause you to repeat an action and buy another item or post a message another time.<br />
    A way to prevent this pop-up about resending POST data is not to use the Back button, but to open links on a page requested from a server by sending a form with POST date in a new tab (window) with a middle-click or a Ctrl + left-click.

  • Pam.conf does not use ldap for password length check when changing passwd

    Whereas /etc/default/passwd on the ldap client says passwords must be 8 characters. This is seen with the pam_authtok_check: minimum length from /etc/default/passwd: 8
    . It is clearly not using the policy from the directory server but checking locally. So I can login ok using the ldap server for authentication but when I try to change the password it does not use the policy from the server which says I only need a minimum lenght of 6 characters.
    I have read that pam_ldap is only supported for directory server 5.2. Because I am running ds6 and with password compatability in ds6 mode maybe this is my problem. Does anyone know of any updated pam_ldap modules for solaris 9?

  • ColdFusion 11 Throws Error Session Variable Undefined, When in fact it is Defined as shown by CFDump.

    I've been having a particularly annoying error with ColdFusion 11, and unable to track down the source of this problem.
    Basically There are a few variables defined in the session scope we check with isdefined a few lines above to make sure they are defined. Subsequent lines may or may not throw a #variablename# is undefined on random lines.
    What can I do to fix this issue? Is this a known bug?

    I am doing isDefined checks for relevant variables when neccessary. The problem is not that the code errors out undefined ... it's that the variable is actually defined and errors out undefined.
    As a simplified example;
    Login.cfm Form supplies form.username and form.password to login_action.cfm then redirects to index.cfm after succesful LDAP authentication. I will not include all lines as it would be too long.

    What is causing this strange and irratic behaviour? The problem is so far I cannot replicate the issue. It is intermittant. The issue only started after upgrading to ColdFusion 11. This code has worked flawlessly for years on CF8.

  • Avconvert: failed to create an Export Session. Check setup.

    I get the message "avconvert: failed to create an Export Session. Check setup" when i try to convert an mpeg video to mp4. Any solutions?

    here we are 4 months (give or take) and 10.7.1 did not provde a fix.  My

    also comes for trying to convert avi files.
    Something else that wasn't fully tested before the release of Lion.
    I have a DivX account and can't use the player unless I wan't to stare at my desktop with whatever open files and folders that are there, listen to the video but not see it and loose ALL control of everything.  I have to efectivly cut the power to the Mac in order to be able to use it.

  • How can I prevent firefox to Offer to save passwords and how to remove the tick checked when I log in to gmail?

    While using firefox I am using, private browsing and not remembering any passwords.
    When I login to Gmail, the login page shows option to type in my gmail id and then password, and at the bottom, it gives the option of checkbox to remember the password next time. NOW, the problem is that, THIS CHECK box is always TICKED (Checked). I don't want it to be checked at all.
    So How can I prevent firefox to Offer to save passwords and how to remove the tick checked when I log in to gmail?
    Thank you so much.

    Hi Imran_Afzal, if you know that setting the cookie has no effect after you close your private browsing session, is it really worth finding a hack to clear the checkbox?
    I believe in order to do that you would need to use an extension or userscript. However, I haven't searched for one.
    ''Note: When searching for a userscript on userscripts.org, be very cautious as many hacked scripts have been posted lately. Check reviews and check the code to make sure it only runs on your Google site before installing.''

    How can I solve this problem? Should I use sessions or maybe something else?
    Pleassssssssseee can you help me?

    If what you want to share among several webapps on the same server is just the login, you just have to configure the single sign on option (see http://jakarta.apache.org/tomcat/tomcat-4.1-doc/config/host.html#Single%20Sign%20On).
    If you want to share more data (some kind of "server session" attributes and not only "webapp session" attribute), I think you have to manage it yourself (using a java.util.Hashtable and the javax.servlet.http.HttpSessionListener for example).

  • How to set password for a zip file and should be checked when reading that

    Hi friends,
    how to set password for a zip file and should be checked when reading that file???
    thanks.
    Praveen Reddy.J

    Heyy man, i think, u did not get my problem.
    all i have to do is:
    i have to create a zip file, and we should secure it with password when creating. and whenever the user wants to open that zip file he should provide correct passowrd otherwise he could not read that file. So, we should check for that also.
    Tanks for reply.

  • Urgent: Gif animation shows only the last frame when reloaded

    I use ImageIcon to show gif animations on screen. I want to use only non-looping gif animation files.
    Always when I show a gif animation for the first time it runs correctly through all the frames.
    However when reloading later the same gif animation only the last frame appears. I want to see all the frames of the animation, not only the last frame.
    So for the first showing of the animation this works well:
         icon = new ImageIcon("first_animation.gif");
           label = new JLabel();
           label.setIcon(icon);Then I show another animation and also it works well:
           icon2 = new ImageIcon("second_animation.gif");
           label.setIcon(icon2);Now I would like to show the first animation again but only the last frame of that first animation appears on screen:
    label.setIcon(icon);And even this alternative way to refresh does not work:
           icon = new ImageIcon("first_animation.gif");
           label.setIcon(icon);
    How can I reload the first animation again so that it shows all the frames not only the last frame???
    I have tried for ex. commands updateUI(); and setImageObserver but they don't seem to help.
    I am only a novice so...
    Please I would really appreciate your detailed advice what lines I should rewrite in my code and how?
    Thank you very much!!

    By flagging your question "urgent", you are implying that either your question is more important than other people's questions, or your time is more valuable than mine (or someone else's answering questions here). Both are not true.

  • Needs to be checked when financial year is closing

    Hi,
    I want to know the things what to be check when the financial period 2006 is closing in SD. like number ranges,material document number range.

    Thank you so much.  But now I understand why you asked if the other boxes should be unchecked.
    I did the following but when I input 4 and change it to a 1. The box for 4 stays checked.  Also when the text field is blank the boxes stay checked.  What do I do make sure they are un-checked. 
    if (event.value=="1") this.getField("SetA1.1").checkThisBox(0, true);
    if (event.value=="2") this.getField("SetA1.2").checkThisBox(0, true);
    if (event.value=="3") this.getField("SetA1.3").checkThisBox(0, true);
    if (event.value=="4") this.getField("SetA1.4").checkThisBox(0, true);
    if (event.value=="5") this.getField("SetA1.5").checkThisBox(0, true);
    if (event.value=="6") this.getField("SetA1.6").checkThisBox(0, true);

  • Avconvert: failed to create Export Session.  Check setup

    I'm trying to convert an mpeg file so its readable on my macbook pro, I have OS 10.7.5.  I right click the file and select Encode selected video file.  For setting I click 1080p.  The next window pops up:

    I also have this very same problem. I ctrl click on my selected video file (avi) and select from the menu "encode selected video files". after I click continue from the "encode media" panel I recieve the same error as above, "failed to create an export session".
    I too am not sure what to do next.

  • Sequence of check when saving customer/vendor

    For customers, I am aware that there are 3 possibilities to check the contents of the entered data before the customer is really saved:
    - Settings of field status group
    - Message control
    - User exit
    Can anyone advise me in which order these settings are checked when saving a customer?
    Best regards
    Martin

    Hello,
    No, you can't. BP will always be created first and then a corresponding supplier/customer will be created depending on CVI configurations.
