Setting up Response Assertion for Cookie

[gubbu gubbu]

I read the docs but couldnt find any example . How can I setup a response 
assertion for "response headers" ? For example I want to compare the 
"host1jvm1"following header to the request .

Set-Cookie: JSESSIONID=4AADDA33814B25F63C1D11F1901DF50F.host1jvm1; Path=/;
