Turn off .lc Web-browser Caching?

[Rick Harrison]

Hi there,

I know this has come up before but
looking through the old archives didn’t
seem to turn up a working answer.

Is there a good way to prevent a web-browser
from re-displaying an image in it’s cache?

I tried using a random number after the .lc URL
such as:

http://www.mysite.com/destination.lc?r=39923959 <http://www.mysite.com/destination.lc?r=39923959>

I have also tried:

put "<meta http-equiv='Cache-Control' content='no-cache' />"
put "<meta http-equiv='Pragma' content='no-cache' />"
put "<meta http-equiv='Expires' content='-1' />”

and that doesn’t seem to work either.

Did anyone ever come up with a good solution?

Thanks,

Rick
