Hi, I have a doubt. In all the browsers that supports CSS PIE also is charging? Does It consume resources? Thanks

The .htc file will *only* be downloaded in Internet Explorer (as only Internet Explorer understands the "behavior" CSS attribute). You can confirm which css attributes a browser is taking notice of using "Inspect Element" (Firebug, Dragonfly, etc.)

However, IE9 *will* load the file but *won't* run the css3pie code as of beta 3. If you wan't to stop IE9 downloading it then you could include the necessary css in a separate css file using IE conditionals - there might also be css hacks that can be used so that only IE 6-8 understands it, if you like going down that route...
