Is it possible to monitor the cookie length/size from the user session?

Is there a way Dynatrace can track the cookie size of a web application?

This is a really good question. Out of the box... I don't think so. You can formulate a request attribute which will pull the cookie value, to which you can then apply it to associated user sessions. When you state what size, what is the type of sizing that your looking for? Character length?
