URL Rewriting (HTTPS)

 Hi guys

I have a simple question,

I have an internal server, currently we can all login using https://intserver1.domain.com/login.aspx

Created a server farm - pointing to intserver1.domain.com

Then created a {HTTP_HOST} pattern rule for intserver1.* for the above

and by default there is already a {HTTPS} rule matches "ON"

Problem is it works well in http://intserver1.domain.com/login.aspx but it doesn't work when I tried https://intserver1.domain.com/login.aspx. The error msg is "The Page cannot be displayed"

Please advise how do I go about fixing the above

Thanks in advance
