apache https 代理不用443端口 登陆成功后自动转向了http请求,请问为什么

如果用443 端口实现ssl 登陆后会浏览器会被强制使用 https的请求,如

     https://ABCQASBIXAPP/ABC/login.jsp  ---> https://ABCQASBIXAPP/ABC/index.jsp

配置如下

Listen 443
<VirtualHost *:443>
  ServerName ABCQASBIXAPP:443
  SSLEngine On
  SSLCertificateFile conf/ssl/server.crt
  SSLCertificateKeyFile conf/ssl/server.key
  SSLCertificateChainFile conf/ssl/ca.crt
<IfModule mod_weblogic.c>
WebLogicCluster 10.6.57.210:9001
MatchExpression *.jsp
MatchExpression *.*
MatchExpression *
KeepAlive on
DynamicServerList OFF
KeepAliveEnabled ON
KeepAliveSecs 30
</IfModule>
</VirtualHost>
<IfModule mpm_winnt.c>
ThreadsPerChild 150
MaxRequestsPerChild 10000
Win32DisableAcceptEx
</IfModule>
<IfModule ssl_module>
SSLRandomSeed startup builtin
SSLRandomSeed connect builtin
</IfModule>
RewriteEngine on
RewriteCond %{HTTPS} !=on

RewriteRule ^(.*)  https://%{SERVER_NAME}$1 [L,R]       

但是不用443 端口 换成其他端口如8443 登陆后 浏览器变成了http显示 ,请问为什么 ? 如

    https://ABCQASBIXAPP:8443/ABC/login.jsp  ---> http://ABCQASBIXAPP:8443/ABC/index.jsp

配置如下

Listen 8443
<VirtualHost *:8443>
  ServerName ABCQASBIXAPP:8443
  SSLEngine On
  SSLCertificateFile conf/ssl/server.crt
  SSLCertificateKeyFile conf/ssl/server.key
  SSLCertificateChainFile conf/ssl/ca.crt
