question about 'register_globals' setting

Hi, I'm using I.E. 6. I noticed that register_globals was set ON in my php.ini file so I changed it to OFF in as per the security warning. I've noticed a side effect. When I submit a form via POST and then go back from the results page, my form has been cleared, i.e.., as if the page has been reloaded. Is this a normal effect of setting register_globals OFF? Is there a way to continue caching? Thanks, Don --- Outgoing mail is certified Virus Free. Checked by AVG anti-virus system (http://www.grisoft.com).
