Using Apache 2.0 (2.0.53) on a particular legacy system, enabling mod_deflate causes directly-served content to be gzip-encoded just fine. However, and this is my problem, content proxied from another server using ProxyPass is not getting gzip-encoded. Wireshark shows me there is no encoding header in the response and the body is in plain text.I have another similar system, also running Apache 2.0 (2.0.52), where the proxied content IS being gzipped, and I can't find any significant difference between the configuration of the two systems.Details:mod_deflate is being enabled using a file /etc/httpd/conf.d/deflate.conf containing:<ifModule mod_deflate.c>AddOutputFilterByType DEFLATE text/html text/xml text/css text/plainAddOutputFilterByType DEFLATE text/javascript application/javascript application/x-javascript application/json</ifModule>The proxying is being done within the <VirtualHost> section using these lines:ProxyPass /mtserver http://localhost:8000ProxyPassReverse /mtserver http://localhost:8000Can anyone point me at a possible reason for one system not compressing the proxied content?
