Apache服务器的反向代理问题

使用Apache2.2进行反向代理，然后第一次进去是正常的，可是点击跳转的话，就出现了这个错误信息：

Bad Request

Your browser sent a request that this server could not understand.
Reason: You're speaking plain HTTP to an SSL-enabled server port.
Instead use the HTTPS scheme to access this URL, please.

比较百思不得其解，求教一下为什么会出现这样的情况，下面是我的Apache vhost配置：

SSLMutex default

listen 9304

NameVirtualHost *:80
NameVirtualHost *:9304

<VirtualHost *:80>
    DocumentRoot "/Apache22/htdocs"
    ServerName 172.27.35.7:80

    #SSLEngine off

    #RewriteEngine On
    #RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [L,R=permanent]
</VirtualHost>

<VirtualHost *:9304>
    ServerName 172.27.35.7:9304
  DocumentRoot "/Apache22/htdocs"

    ProxyVia on
    ProxyRequests off
    ProxyPreserveHost on

    SSLEngine on
  SSLProxyEngine On
  SSLProtocol all -SSLv2 -SSLv3
  SSLHonorCipherOrder on
  SSLCipherSuite HIGH:!RC4:!MD5:!aNULL:!eNULL:!NULL:!DH:!EDH:!EXP:+MEDIUM
  SSLCertificateFile "D:/Apache22/conf/openssl/server.crt"
  SSLCertificateKeyFile "D:/Apache22/conf/openssl/server.key"
  SSLCertificateChainFile "D:/Apache22/conf/openssl/ca.crt"

  <Proxy *>
        Order deny,allow
        Allow from all
  </Proxy>

    #<Location /mbi/appDownload>
    #   Order deny,allow
    #   Allow from all
    #</Location>

    ProxyPass / http://172.27.35.12:8080/
  ProxyPassReverse / http://172.27.35.12:8080/  

  ErrorLog "logs/error.log"
  CustomLog "logs/access.log" common

  <Directory />
    Options FollowSymLinks
    AllowOverride None
    Order deny,allow
    Allow from all
  </Directory>
</VirtualHost>

你跳转的地址是gttp但是访问的的确是https协议

参考ProxyPassReverse dropping HTTPS
注释掉下面的行

#ProxyPreserveHost On
