--enable-sigchild, but still have "invalid logins"

Hi group, Here are the build params used for PHP4.0.0 (finally off of RC2 :) ) ./configure' '--enable-sigchild' '--with-oci8' '--enable-track-vars' '--enable-trans-sid' --with-apache=../apache/apache_1.3.12' Running Oracle 8.1.5, with Apache, on a Sun unix box. When the user logs in, Oracle works as planned. If the user accidentally hits the back button and reloads the page. You'd think that by merely exiting the browser and relaunching it, then relogging in would fix the issue. But instead he gets: Warning: OCISessionBegin: ORA-01017: invalid username/password; logon denied in menu.php on line 10 Line 10 is $connection = OCILogon($username,$password,$db); The username, password & db values are all valid, and I can easily log into Oracle at that moment via SQL+. I thought enable-sigchild would resolve the issue... Thank you, Paul
