stefan_martinek on "W3 Total Cache & CAPTCHA"

I use "Really Simple CAPTCHA" plugin on my website and I had to turn off the "browser cashing" in W3 in order to keep Captcha changing (on the first CAPTCHA entry it kept the old value and after an error message the CAPTCHA got correctly reloaded). Is there a better way (e.g. turn off browser caching in the contact page or something else)? Thank you.

Stefan
