GETレスポンス（スクレーパー）から「セットクッキー」の一部が欠落していますか？

Question

私が使用して認証しようとしている：https://sso-prod.sun.ac.za/cas/login が、私は私の最初のGETリクエストで受信するクッキーは、ここで不完全

ように見えるが、Firefoxが受け取るものです：

が、クッキー私は私の要求から得る：

Cookies: 
    "" 
    BIGipServerpool_cas_sso_443=1954670738.47873.0000; path=/ 
    JSESSIONID=828CAEC2F2D093C1331494B5B719D48F; Path=/cas; Secure 

。
