我有一个无法解决的问题。我把Apache配置写成这样：

<IfModule mod_ssl.c>
  <VirtualHost *:443>

    ServerAdmin aa@aa.com
    ServerName xx.xx.xx.com

    DocumentRoot /var/www/html

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined

    SSLEngine on

    SSLCertificateFile /etc/ssl/localcerts/apache.pem
    SSLCertificateKeyFile /etc/ssl/localcerts/apache.key

    SSLProxyVerify none
    SSLProxyCheckPeerCN off
    SSLProxyCheckPeerName off

    SSLProxyEngine on

    ProxyPass /bdn/ https://test.yy.it/
    ProxyPassReverse /bdn/ https://test.yy.it/

    RequestHeader unset Accept-Encoding

    Substitute "s|https://test.yy.it/|https://xx.xx.xx.com/bdn/|n"
    FilterDeclare NEWPATHS
    FilterProvider NEWPATHS SUBSTITUTE "%{Content_Type} =~ m|^text/html|"
    FilterProvider NEWPATHS SUBSTITUTE "%{Content_Type} =~ m|^text/css|"
    FilterProvider NEWPATHS SUBSTITUTE "%{Content_Type} =~ m|^text/javascript|"
    FilterProvider NEWPATHS SUBSTITUTE "%{Content_Type} =~ m|^application/javascript|"
    FilterChain NEWPATHS

  </VirtualHost>
</IfModule>

反向代理工作，但我松散的CSS，javascript，图像，...为什么？？？我读过一些解决方案在网上：

• http://makandracards.com/makandra/32973-reverse-proxying-web-applications-with-apache-2-4+
• https://serverfault.com/questions/561892/how-to-handle-relative-urls-correctly-with-a-reverse-proxy

但是没有一个能用我用的是：

• S.O. Debian 8软件开发人员
• Apache 2.4.10版

请帮帮我！非常感谢。
