reverse proxy / extfilter not working

[V B <forums@xxxxxxxxxxxxxxxxx>]

Gents,

  This appears to be a common issue....

  Whilst you are able to execute ExtFilters on local files, a Reverse Proxy configuration does not work the same way.

  This has been reported here:

   http://objectmix.com/apache/706472-proxypass-extfilter.html

   

  Config:

<VirtualHost *:80>

        ServerAdmin webmaster@xxxxxxxxxx

        DocumentRoot /usr/local/apache/htdocs/

        ServerName search.domain.com

        ServerAlias search.domain.com

        ErrorLog logs/search.domain.com-error_log

        CustomLog logs/search.domain.com-access.log combined

        <Proxy balancer://domain.com>

                BalancerMember http://ip1

                BalancerMember http://ip2

        </Proxy>

        ExtFilterDefine fixtext mode=output intype=text/html cmd="/bin/sed s/html/HTML/ig"

        

        SetOutputFilter fixtext

        RewriteEngine on

        ProxyPass / balancer://domain.com/

        ProxyPassReverse / balancer://domain.com/

</VirtualHost>

I am completely out of thoughts on this matter.  If you guys could help, that would be wonderful....

Thanks!

Vasiliy

PS  Removing the revproxy, and things work like a charm.
