Http_proxy using HTTP/1.1?

Server NGINX
1

Hello all,

Is it possible to have the proxy module communicate with back-end
servers using HTTP/1.1? The back-end servers that I am proxying, in this
case, require the Host header as part of the HTTP/1.1 protocol.

Thanks for any ideas you may have.

Hey Ian,

I’m not sure but i think i might be having the same issue. I have a
swiftiply server as backend that requires host header to select the
right application to serve. It seems my backend server is not getting
these as I am alwasy served the default application no matter what i
write in the url…

If you find anything, let me know.

This didn’t seem to work for me. It’s still sending “HTTP/1.0” in the
request and that seems to kill the connection to the virtual server on
Apache.

Found my problem. I was sending the wrong host (duh). Setting the header
host with $host would send to my swiftiply server the host
“blabla.mynginxserver.com” which is not recognized and so returns the
default application.

I actually found my problem. Headers are being sent to the proxied
server that are interfering.

Is it possible to tell nginx to not send certain headers to the proxied
servers?

Thanks.

If its absolutely essential for you to have HTTP 1.1 behaviour between
proxy and upstream then give lighttpd 1.5 (out of svn) a try

svn checkout svn://svn.lighttpd.net/lighttpd/trunk/

just set an empty string as header and nginx won’t send it to back-end.
for example:

proxy_set_header Accept-Encoding “”;

That was easy.

To stop a header from being sent to the proxied servers just set the
header to blank!

For example:
proxy_set_header Authorization “”;
proxy_set_header User-Agent “”;

HTH someone else.
