When I am making changes on my localhost, it is not working. I am on windows 7 but when I copy the file in which the changes were made, and try to execute them in Windows XP, its working. I as I asked someone who has a lot of knowledge on this and they said it is a configuration issue.

Someone else told me it was because of output caching, so I disabled everything and tried, even then there was no response. Can anyone tell me how do I go about it?
