I am trying to configure an apache reverse proxy serving SSL where it will inflate gzip posts and then deflate (gzip) the response on the way back out. I have all SSL, reverse proxy configuration working. I've tested and verified those pieces. What I'm trying to do now is enable mod_deflate to do the unpacking of the requests and the re-packing of the response. This is simply to minimize bandwidth usage. I have verified the client is submitting gzip data and also sending the HTTP Header "Content-Encoding" as "gzip" (not quite sure if that matters at this point). The data being proxied is not being upackaged (deflated), and in the httpd error logs, I see [Tue Oct 23 14:02:24 2012] [error] an unknown filter was not added: INFLATE
I have found the configuration docs for this at http://httpd.apache.org/docs/2.2/mod/mod_deflate.html and some various other emails complaining of this problem turned up via google, with no real answer emails. I have tried various configurations in my VirtualHost with/without Location of http_bind. I also cannot find the input filter by type directive similar to "AddOutputFilterByType". I would have expected there is a AddInputFilterByType, but there is not one. Note that I also have LoadModule deflate_module modules/mod_deflate.so so it isn't something as simple as "you forgot to load the module". Sample configuration: <VirtualHost _default_:5555> ServerName test.com:5555 ErrorLog logs/test.com-error.log CustomLog logs/test.com-access.log common SSLEngine on SSLCipherSuite ALL:!ADH:+HIGH:-MEDIUM:-LOW:-SSLv2:-EXP SSLCertificateFile /var/www/keys/test.com.crt SSLCertificateKeyFile /var/www/keys/test.com.key SSLCertificateChainFile /var/www/keys/RapidSSL_CA_bundle.pem SetInputFilter INFLATE SetOutputFilter DEFLATE SSLProxyEngine On ProxyRequests Off ProxyPreserveHost On <Location /http_bind> SetInputFilter INFLATE SetOutputFilter DEFLATE ProxyPass https://test.com:5443/http_bind ProxyPassReverse https://test.com:5443/http_bind </Location> <Proxy *> Order deny,allow Allow from all </Proxy> </VirtualHost> Again, the only log that I can find that indicates the problem is [Tue Oct 23 14:02:24 2012] [error] an unknown filter was not added: INFLATE Is there some other directive that I may be missing to unpack the posted gzip requests?
