Reverse proxying and specific output filter chain manipulation

[Thomas Eckert <thomas.r.w.eckert@xxxxxxxxx>]

In a simple reverse proxy setup, such as
<Proxy balancer://cd107d9706d71153bafd4ab15f1c6b5d>
        BalancerMember http://mydomain.org status=-SE
</Proxy>
<VirtualHost 10.10.10.10:80>
	ServerName secure.mydomain.local
	SSLProxyEngine On

	RequestHeader set X-Forwarded-Proto http
	<Location />
		ProxyPass balancer://cd107d9706d71153bafd4ab15f1c6b5d/ lbmethod=bybusyness
		ProxyPassReverse balancer://cd107d9706d71153bafd4ab15f1c6b5d/
		ProxyPassReverseCookieDomain balancer://cd107d9706d71153bafd4ab15f1c6b5d/
		Include conf/proxyhtml.conf
		SetOutputfilter INFLATE;xml2enc;proxy-html;DEFLATE
		Require all granted
	</Location>
</VirtualHost>

how do I manipulate the output filter chain from the reverse proxy to the backend ? E.g. I want to discard the Accept-Encoding
header when talking to the backend but I don't want to use RequestHeader unset Accept-Encoding globally since that kills
compression support to the external clients as well.

Cheers,
