HTML Content Filtering with Snort

[eth><]

Hi Guys

i tried to make some filtering of HTML content, like <iframe src=" ; or <a href="http, or <img src=", etc.. but i had no success on the webfilter and the adware filter, so is it possible to do that on the snort engine?

if yes, how ?if no, where and how can i do that?

thanks 2 all
