Perl and refresh button, save twice?
Hi guys,
I am writing a simple script save_me.cgi that can save the data in form.html into a txt (data.txt)file.
But when user click "refresh" button one the browser on page save_me.cgi, the data will be save again in the data.txt.
could someone help me on this issue?
a studpid way might be check the whole file and see any repeat records. but I would try to avoid this if possible.
Thanks
