alphanumeric string is generated and stored as a session variable. The
string is also used to generate an image showing the string. A user inputs
the string as shown in the image and on submission if the user input matches
the session variable, then we have a match.
The problem is that if a test fails, the image does not refresh for the
following browser/OS combinations:
Mac 10.2 IE 5.2
Mac 10.2 Safari
Seems to work fine in all browsers on my XP box. I have not been able to
test on Linux yet.
Sample: http://www.aftershockweb.com/test/
I'm using CFCONTENT to display the image through an iframe; I'm also using:
<CFHEADER NAME="Expires" VALUE="Sun, 06 Nov 1994 08:49:37 GMT">
<CFHEADER NAME="Pragma" VALUE="no-cache">
<CFHEADER NAME="cache-control" VALUE="no-cache, no-store, must-revalidate">
The only way I am able to get the image to reload is to use the browser
refresh button. Does anyone have an idea how to force the page to refresh
the image?
Thank you,
Stan Winchester
