Is it possible to remove the referer completely using Nginx reverse proxy configuration.
Set proxy header to an empty string.
proxy_set_header Referer "";

I'm using NGINX as a proxy cache server for my image optimization, and want to pass the accept HTTP header from the client's request to the backend through the proxy.
Is this possible and if so, how can I do this?
The reason why I want to do this is that because the backend decides based on the accept header the file format of the response.
Thanks in advance for your help!
You need to set
proxy_pass_request_headers on;
in your proxy settings block
So my nginx is configured like image below
so when i set the PROXY_ADDRESS_FORWARDING to TRUE, it would be redirect to https://example.org:8080
what should i config on the Keycloak so it could redirect correctly ?
Well, your question here is not very clear to say the least.
But since you are having problems with nginx proxy I would suggest you set proxy_set_header Host $host; in your nginx conf, this way nginx will not override the Host header when proxying.
If that does not solve your problem, please provide more information about you what you want to achieve and what's going wrong.
I have an instance of Nginx Plus deployed as a reverse proxy. The proxy app returns a "set-cookie" header in the response which I'd like to modify (the domain associated with the to-be cookie):
Change
set-cookie:key=value;Path=/;HttpOnly;Domain=my.domain.net
to
set-cookie:key=value;Path=/;HttpOnly;Domain=new.domain.com
Needless to say I can't modify the application to use something like an outbound rewrite rule.
The Nginx http proxy module has two directives which manipulate the “Set-Cookie” header in the response from the upstream server.
proxy_cookie_path can change the path attribute of the “Set-Cookie” header.
proxy_cookie_domain can change the domain attribute of the “Set-Cookie” header.
The Upstream server is wowza , which does not accept the custom headers if I don't enable them on application level.
Nginx is working as a proxy server, from the browser I want to send few custom headers which should be received and logged by Nginx Proxy but before forwarding request to upstream server those headers should be removed from the request.
So upstream server never come to know that there where any custom headers.
I tried proxy_hide_header as well as proxy_set_header "<header>" "" , but seems like they apply to response headers not the request headers.
And even if I accept to enable the headers on wowza, then again I am not able to find a way to enable headers at server level for all application. Currenlty I have to add headers to each newly created application which is not feasible for me to do.
Any help would be appreciated.
The proxy_set_header HEADER "" does exactly what you expect. See https://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_set_header.
If the value of a header field is an empty string then this field will not be passed to a proxied server:
proxy_set_header Accept-Encoding "";
I have just confirmed this is working as documented, I used Nginx v1.12.
I have a Nginx websocket reverse proxy and I would like to hide a HTTP header from the client request.
proxy_hide_header hides the server response headers and can't be used for hiding client request headers.
I would like to do that because the websocket server behind nginx doesn't work well with the websocket extension "permessage-deflate" so I would like to remove the Sec-WebSocket-Extensions header from client requests.
You can set a header value to void and Nginx will drop it :
proxy_set_header Sec-WebSocket-Extensions "";
The official documentation explains the correct way to remove a client request header:
If the value of a header field is an empty string then this field will not be passed to a proxied server:
proxy_set_header Accept-Encoding "";
In case that wasn't clear, this is more than just a workaround to mask the value; the entire header will be dropped.
