[users@httpd] mod_deflate: an unknown filter was not added: INFLATE

["GOUIN Fabrice (EXT STERIA)" <ex...@sncf.fr>]

Hi all,

I'm trying to use mod_deflate to decompress a compressed request from a
client on my reverse-proxy.

First, I'm confused with the Apache documentation
http://httpd.apache.org/docs/2.2/mod/mod_deflate.html#enable. In fact,
for input decompression, the doc tells to use "SetInputFilter DEFLATE".
Shouldn't it be "SetInputFilter INFLATE"??

Anyway, whatever configuration I choose for my virtual host, it fails
when I post a request with a "Content-Encoding: gzip" header and a gzip
request body:
- if I use "SetInputFilter DEFLATE", the error is "Internal error:
proxy: prefetch request body failed" and my rproxy returns a 400 BAD
REQUEST error
- if I use "SetInputFilter INFLATE", the error is "an unknown filter was
not added: INFLATE" and the target website gets the compressed body

I tried that with Apache 2.2.17 and 2.2.19 with the same result.

Any idea ?

Thanks,

Fabrice GOUIN
