The HTTP to HTTPS Redirection allows you to force clients who browse to the URL of the
web listener using http:// to be redirected to the https:// URL. This option requires that you enable
both port 80 and 443 in the web listener under Client Connection Type.
When this option is enabled, the ISA Firewall will send an HTTP/1.x 302 Object Moved response
back to clients who hit the http:// URL, causing the client browser to redirect to URL specifi ed in
the Location HTTP Header.

翻譯如下：當你在web偵聽器當中啓用了http to https 重定向的話，那麼當客戶端在URL當中輸入http:的時候isa會返回一個HTTP/1.x 302 Object Moved response，告訴客戶端把http：改成https:
大體意思就這這樣，本來想做實驗截個報文實驗一下的，但又因爲怕麻煩，所以沒有用實驗證明。
