Apache SSI不能与替代命令一起使用

我在我的httpd.conf中有一个虚拟主机,充当反向代理。 它工作正常,我能够取代文字与我想要的,但我想包括一个文件..

ServerName example.cm ServerAlias www.example.cm Options +FollowSymLinks Options +Includes RequestHeader unset Accept-Encoding RewriteEngine on RewriteRule ^example w [L] FilterDeclare CUSTOMFILTER FilterProvider CUSTOMFILTER SUBSTITUTE resp=Content-Type $* FilterProvider CUSTOMFILTER SUBSTITUTE resp=Content-Type $/html FilterDeclare Sub FilterProvider Sub SUBSTITUTE resp=Content-Type $text/html FilterDeclare SSI FilterProvider SSI INCLUDES resp=Content-Type $text/html <Location /> ProxyPass http://www.example.com/ ProxyPassReverse http://www.example.com/ AddOutputFilterByType SUBSTITUTE text/html Substitute "s|example|replaced word|ni" Substitute "s|(<head>)|$1<!--#include virtual=\"/var/wwwroot/example.cm/include.shtml\"-->|i" </Location> 

它工作正常,但是当从浏览器的HTML中查看源代码时,它实际上用我input的代码replace标签,但是不执行或分析包含命令。 查看来源:

  <head><!--#include virtual="/var/wwwroot/exampe.cm/include.shtml"-->
