What site and which cookie (if you can be more specific)? Usually the site-specific preferences work great for me, I could give it a try if you want.

If you open the Cookie Sheet (by clicking on the Cookie icon in the status bar at the bottom), you can select a cookie and change its status to Rejected.[/quote]

Am I to understand that if you do this, then theat cookie is supposed to be rejected [b]from now on[/b]? If yes, that would be most excellent. But it seems from the original poster's comments that's not the case.

I can see where this would be useful. For example, some sites have useful cookies like site preferences or remembering a login. But they also have, from the same domain, site tracking cookies I'd rather block.

I don't think this works. I've got .*adbrite\.com/.* on my block list, yet the site [url]www.popoholic.com[/url] seems to be able to set a cookie with the domain .adbrite.com

I guess that makes sense since the cookie is technically coming from popoholic but no data is transferred from adbrite.

Troy, can you clarify the behavior here?

Well what I was thinking is that OmniWeb was allowing the cookie through because it was getting created by popoholic (and pointing to the ad site). But I'm actually not seeing this now. Deleting the cookie, adding "adbrite" to the blacklist and reloading the page seems to be working for me.

FWIW there should be no way popoholic.com could set or read a cookie from adbrite.com. That would be a [b]huge[/b] security hole!

Now to Handycam who has .*adbrite\.com/.* in his block list. I am not quite sure how OW works but I think possibly as these are regexes there is confusion to what the / do. If the / in a block filter are actually delimiters for the regex (which I am guessing they probably are) then that could be why it is failing. Try blocking /.*\.adbrite\.com/ instead and see if that fixes it.

That's a good point. Silly of me to think otherwise.

Handycam's expresion should work. OmniWeb validates each expression as they are entered and marks invalid expressions red to make it easier to identify problems.
