When calling ExpandTemplate(), this generates an header of its own. The problem is what if we need to add a cookie after we have called ExplandTemplate(). There is already an header. As far as I know, from all the threads I have read, it seems that the only way to create a cookie in WWC, is the create a header and write that header. Which means, we will end up with two headers. And, this is exactly what happens.

How to solve this problem?

Some will say that we should only call that function once and call it with the parameter of the header which could include the cookie. I don't believe in that. In several projects, I need to call that function at least two times per call before returning the content to the user. And, we are also adding some HTML on our own. And, then, after, the business logic might decide to add or not a cookie. That is a situation.

By default, once the process kicks in, we have access to Response, Request, Server and Session objects. But, where's the header. If there would be one, we could have access to it from anywhere and just add items to it. It seems that when we want to do it we have to create the object. If that would be the case, and if ExpandTemplate() would not deal with that, we would be ok. Having them independent would make things a lot easier.
