Should be easy question but

i have a text file that i’m importing to flash…then the user can enter text into an input box and flash sends it to a php script that appends the new text to the end of the old text file. However, the problem is that when flash try’s to reload the new text it retrieves only the old file because the browser has stored the text file. I know how to configure my browser so this doesn’t happen but most of my users don’t. Can i put a header in the text file that will tell the browser not to save the text file???
Thanks!
