Ssi, reverse-proxy and compression

Server NGINX
1

Hello,

we’re using ssi with reverse-proxy on NginX 0.6.34, but have a problem
when contents is compressed on the fly by the backend.
As we can’t disable this on the backend, we would like setup NginX to
don’t send the “Accept-Encoding” header to it, or to decompress this
contents before processing ssi tags.

I don’t find how to set up that, so actually I simply replace the
Accept-Encoding this way :
proxy_set_header Accept-Encoding none

Is there a “better” way to do that ?

Thanks in advance,
Olivier

HTTP compression requires HTTP 1.1 and from what I know, nginx uses HTTP
1.0 for proxying. In that case, there should be no compression in a HTTP
1.0 response. So it sounds like the backend is sending compressed
response when it should not do so.

RFC 2616 - Hypertext Transfer Protocol -- HTTP/1.1

Actually, HTTP/1.0 clients usually understand compression.
