Trouble removing cookie

Question

Hi,&nbsp;&nbsp;So I'm attempting to remove a cookie, nothing to fancy.&nbsp;&nbsp;&nbsp;I've got this basic irule:&nbsp;&nbsp;&nbsp;when HTTP_REQUEST {&nbsp;   HTTP::cookie remove "my-cookie"&nbsp;}&nbsp;&nbsp;&nbsp;That didn't work, so I put in another section:&nbsp;&nbsp;&nbsp;when HTTP_RESPONSE {&nbsp;  HTTP::cookie remove "my-cookie"&nbsp;}&nbsp;&nbsp;&nbsp;No matter what, the cookie persists. What am I doing wrong?&nbsp;
