Turn off .lc Web-browser Caching?

[Rick Harrison]

Hi Tom,

Unfortunately, I wanted to stay away from
javascript because some people turn it off
in their web-browsers for security reasons.

The solution I finally used was to just rename
the image so that it looked new to the web-browser,
and then update the database with the new name.
I did it using LiveCode so no javascript was required.

Thanks for your suggestion anyway.

Rick
