Hi Axel-Stephane!
I see why you can suspect Apache httpd of setting these headers, but AFAIK from
having used Apache 2.0.x
> and mod_proxy for a number of years, Apache does not "rewrite"
headers unless you do so explicitly in the
> configuration.
I agree but, really, I can't figure out. Theres no such directives in
my configuration. But I gonna check out by the third time. The odd
thing is that other files, like GIF and JPG which also backend server
generates the 'Cache-Control' this rewrite doesn't happens.
You will note that in the first case the application replies HTTP/1.0 and in
the second, HTTP/1.1. Did you use wget in both cases ?
Yes, I did. Maybe due a 'KeepAlive On' in apache....
By the way, wget uses HTTP 1.0 with a 'Connection' header. it is a
violation, isn't it?
Could you possibly snoop/sniff the traffic apache->server using
snoop/tcpdump/ethereal ?
That could shed some light on who sets the headers the way the client receives
them.
It would however require that you install the reverse proxy and the application
on different servers.
Here comes wget->apache connection:
