Code to force browsers to reset? Can't see updates
When I make updates to my iWeb site, they cannot be seen unless I reset my browser. It's become a mess; some clients think I haven't updated my site in 2 years! Is there code I can embed in a snippet to force their browsers to reset? TIA
adding a question mark in the url acts as a request to the server for info (cgi/fcgi/ajax request or whatever) and that forces the server (server side and not browser cache) to serve the latest info (the page).
it'd done in the past sucessfully:

HT4623 I can't see update option in settings
I can't see update option in settings
The option to update without the computer (Over the air) was made available with iOS 5. If your iDevice is using a version of iOS lower than 5, you will need to use iTunes on your syncing computer to perform the upgrade. Use the Apple link below as a guide for the upgrade.
http://support.apple.com/kb/HT4972
Also read the instructions from the section entitled "Update your device using iTunes" at the link below.

Information regarding transferring purchases from your iDevice to iTunes on your syncing computer can be found at the link below.

Can't see updates available in App Store
Does anyone else have a problem with updates not showing up in the Updates tab? I've got an update in the dock showing but nothing ever appears in the tab in the App Store app. It's not a problem when it's an App update because I can click in the Purchases tab and manually click the Update button but this is clearly a system update. I've got auto updates enabled and after 3 days it still hasn't updated. Short of re-installing my Mac, any tips?

Can't see updates for some Apps
Hi! I have a problem with the Apps in iTunes.
I know that TomTom have released yesterday a new version (1.7) of all their navigators. I have TomTom Italy and TomTom Western Europe. For some unknown reason, when I checked for new updates, it only displayed the new version for the Italy app (and some other apps, of course). So I updated it, thinking that maybe the WE version would be available in the next hours. But still, after more than 24 hours, I have no updates for the Western Europe App.
I've already downloaded updates for some other Apps, so I don't know what's going on.
I've checked in the TomTom page in iTunes and the new version is there but I don't want to download it, because I want iTunes to see it, otherwise I can't trust it anymore for all my Apps updates.
What can I do? Is this a knows issue?
Thank you so much. Bye!Please, can someone help me?
I'm not the only one having this problem:

I can not see PR 1.3 update in My N900 RX-51 Vodaf...
Hello, I have Nokia N900 RX-51 with Vodafone sim here in the UK but I can not see update for PR 1.3 in the app manager. I have checked app manager couple of times but could not find any update. Any one can help me please ???
ThanksYes... Seriously Nokia... why the announcement when they're not available everywhere..
the funny thing is that I have been trying to search for threads about people not getting this update... and there are not many... either Nokia users are too "patient" to wait for anything from Nokia or they simply gave up already.... -

I have a Mac 10.6.8. Just installed Airport Express. I can't see any base stations. I did a hard reset on the Airport Express, turned off all devices, turned them back on. I see plenty of Airport networks in the neighborhood. How can I tell if I have a Mac problem or an Airport Express problem? Airport Express blinks Amber.
Obviously, I'm still using ethernet to be able to reply to this.
Alright, use the same ethernet cable to plug directly into the airport express. This will FORCE the airport utility to now see it regardless of weak signals & interference. You can set it up that way.
BTW, what is the original intent on the express? -

Hi,
I have been working on a small game, and have been able to make most of it run.
However, every now and again when i try to start it, it loads the frame and graphics, but don't start the game loop.
I think i have been starring at it too long, because i can't see WHY?
Here is the code, i assume its something connected to the boolean "waitingForKeyPress"
