Please help me-it's urgent,maintaining session and security using cookies.
hi folks,
i presently developing a web site for an engineering colleege ,i am facing prob in maintaining the session using cookies,and destroying a cookie and keeping security to the user,There are four links on my webpage ,including a logout link,when i click the other links other than the logout,it works perfectly,and when i click the logout link,i am not able to disable the cookie and still able to visit previous pages by clicking the back button.please give a suggestion as such to disable the cokie and maintain the security for my web site.
Thank u....
Try out this login if it helps you.
Create a bean that stores some String value. Then make a object of this bean using the useBean tag with session scope when a user logs in. Store the name of the user in the bean and also set the same name value in the Session object. Then on every JSP page compare the value set in the session object with the bean variable (which will be having a session scope). If the value match, then the JSP page output must be displayed to the user. Then on the logout link, invalidate the session object using the invalidate() method of the session class. As a result now when you will try to navigate back to the old JSP page, null will be returned to you when you will try to retrive the name value from the session object. And since this null will not match with the value in the bean, you should not proceed further with generating the output. Hope this help

Lightroom 4.4 keeps crashing saying "Lightroom encountered an error when reading from its preview cache and needs to quit" please help. I've tried reinstalling it and everything Windows 8.1
I assume you know where your catalogue file (the lrcat file) is located. In the same folder is a previews lrdata folder which you should delete or rename in Explorer, then start LR again.
If I've made incorrect assumptions above, sorry, and we'll go back over it from the start.

Dear Apple,
I have an iPhone 4 32GB (black), i bought from softbank, japan. Now, I have recently finished a graduate and i'll comeback home in Laos. But i can't continue to use my iphone.
Could you please help me to unlock my phone so I can use it with other carrier Sims. I would appreciate it.
Please let me know if you could help me out. Thanks again.
<Edited by Host>Like ckuan said, Apple does not unlock iPhone; your carrier does, provided that the carrier offers this service.
Unfortunately, SoftBank does not offer authorized unlocking of iPhone.
Your best option is to sell this phone and buy another iPhone from the carrier of your choice or better buy a factory unlocked iPhone so you would be able to use it with any compatible GSM carrier around the world. -
I got my Iphone 3gs unlocked, but Navigation and Compass are not working. Please help if anybody had faced this problem and got it resolved.
Only the carrier that the iPhone was locked to can unlock. There you go, hacking void any support from this forum.

Same for the FaceTime function (but if it is ON, there will be an icon): Settings App > FaceTime > [turn it on and set you Apple ID. http://support.apple.com/kb/HT4319 -
Hello, I was wonderin gif you can please help me, my daughters iPod is disabled and I can't open it.
Place the iOS device in Recovery Mode and then connect to your computer and restore via iTunes. The iPod will be erased.
iOS: Wrong passcode results in red disabled screen
If recovery mode does not work try DFU mode.

To restore from backup see:
iOS: How to back up
If you restore from iCloud backup the apps will be automatically downloaded. If you restore from iTunes backup the apps and music have to be in the iTunes library since synced media like apps and music are not included in the backup of the iOS device that iTunes makes.

hello my iphone 3gs just been stolen how can i block the iphone and how could i track it i don't know for sure if i have find my iphone? please help i got many accounts on it and i don't have a passcode :((
It was never free for the 3GS.
It is if the initial sign-up is done on an iPhone 4, iPad or iPod touch 4th gen.
From http://support.apple.com/kb/HT4436:
After I sign up for Find My iPhone for free, can I use it on other iOS devices?
Yes, if your devices are running iOS 4.2. For example, you can sign up for Find My iPhone for free on your iPad and use the same account information to sign in to MobileMe on your iPhone 3GS and turn on Find My iPhone. -
Please Help! I've got a WRT54GX2 that I used for 2 year...
Please Help!
I've got a WRT54GX2 that I used for 2 years with no problems.
I recently tried to set up network with different IP DSL (Bellsouth).
The problem is the computer can not "locate" wireless router. Is this due to the Westell modem not being "bridged".***Note: Make sure that the modem is Bridged and the router is set-up to the Instructions I first gave you. If you still have the issue then follow the below steps. At this point you should find out what is your,
IP Address =
Default Gateway =
Subnet mask =
and provide us with that information.
You can get this info by clicking on Start>>Run>>type "cmd">>click ok, now a black command prompt box will open, type in ipconfig /all
You should see an IP address and default gateway of 192.168.x.xxx
you should see a subnet mask of 255.255.255.0
At this time you should power cycle your router and then the modem by removing the power cable from the router, then remove the power cable from the modem. Wait about 60 seconds and plug in the modem and them plug in your router. wait till all the lights on the modem and router are back on. try to connect.
If it still does not work and the IP address is not what I stated, then you will need to reset the modem by holding in the reset button on back of the router for 30 seconds, this will bring the router back to the factory defaults and will remove any prior settings.
Good Luck,
Ttech

I'm not sure where to post this, but I'm going to start here... I have been having this issue and its really beginning to scare me.
*_The Problem:_* I keep getting a message with a RED Exclamation Sign and its titled "IP Configuration" and says this: *123.456.0.1 already using DHCP 123.456.0.100*
I have been clicking okay, but finally one day got annoyed and called the mac people to get help and... they didnt help a bit.
So now I am trying to find help from others.... please help. give as many suggestion as possible and i'll continue to google for help. Thanks.
*So is someone else using my address?*
*Is someone able to see my screen and information and stuff?*
*Why is this happening?*
Please answer these questions if possible.To really help, a description of how the network you use to get online is configured is needed. Are you using wireless? Are there other computers that use this network and if so, what operating system are they running? What sort of router and modem are you using? etc.
So is someone else using my address?
Either another machine is using your IP address, or something is wrong with the DHCP server.
Is someone able to see my screen and information and stuff?
Probably not.
Why is this happening?
My guess is that the firmware on your router needs to be updated. -

I can't update my iPad to iso 5 please help. When I go to settings and then to general it doesn't have an update button for "check for updates". Thanks
If you have an iPad 1, the max iOS is 5.1.1. For newer iPads, the current iOS is 6.0.1. The Settings>General>Software Update only appears if you have iOS 5.0 or higher currently installed.

iOS: How to update your iPhone, iPad, or iPod touch
http://support.apple.com/kb/HT4623
If you are currently running an iOS lower than 5.0, connect the iPad to the computer, open iTunes. Then select the iPad under the Devices heading on the left, click on the Summary tab and then click on Check for Update.
Tip - If connected to your computer, you may need to disable your firewall and anitvirus software temporarily. Then download and install the iOS update. Be sure and backup your iPad before the iOS update. After you update to iOS 6.x, the next update can be installed via wifi (i.e., not connected to your computer).
