Very Computer

Hello,

I have setup an apache proxy, which seems to work fine. But, I found
out that it doesn't not answer back http/1.1 with a http/1.1 response.
The request comes in as 1.1, but the proxy answer back with 1.0. Is
there some special configuration I need to set in httpd.conf for it
to answer with a 1.1 response?

When I send traffic to the backend machine it will answer with a 1.1
response just fine. We are using the same version of apache for both
the proxy and actual backend server.

Any hints as to what I'm missing? Thanks.

the mod_proxy that comes with Apache is a 1.0 proxy.  By the rfc's,
it's not supposed to return a 1.1 response, since it doesn't support
the advanced cacheing features of http/1.1.

Apache enforces this by checking the r->proxyreq flag just before
sending the headers.  If this flag is set, Apache downgrades the
connection to a 1.0 (closed).

There are other modules that enable 1.1 responses from mod_proxy, but
AFAIK none of them are constitute a full HTTP/1.1 proxy.  However in
your circumstance, you appear to me using mod_proxy as a reverse-proxy/
gateway, so this shouldn't be a big problem.

A simple way around this is to comment out the appropriate lines in
src/main/http_request.c and rebuild apache.

YMMV

And if you want to enable KeepAlive on reverse-proxy, you could try
this:

Hello,

What does using keepalive do for me? How is that different than the
standard keepalive directive normally used with Apache?

Thanks

No more keepalive when you use Apache as a reverse-proxy. You could try:
        % telnet reverse-proxy 80
        GET / HTTP/1.0
        Connection: Keep-Alive

        HTTP/1.0 200 OK
        ...
        Connection: close
And the connection is closed.

With the patch, the HTTP response is:
        HTTP/1.0 200 OK
        ...
        Keep-Alive: timeout=15, max=100
        Connection: Keep-Alive
And the connection is not closed, so this speed up browser's requests
(very interesting for SSL).
