Cache and Apache2?

Hello, I have been experimenting with Apache2 on Win32, and have noticed something different when I access pages - it seems like things are being cached different. For example, phpmyadmin does not work correctly. Its like I have to always click the "reload mysql" link... Stuff like that... I also have a gallery application (photo gallery), and the setup php when I run it loads, but when I click the button to go to step 2, its like it just reloads the page instead of going to the next page... seeming to me like it has the page cached, so its not going to step 2.... Please if you know what this might be, any help is appriciated! Thanks!
