If you want to serve serve content from multiple services or multiple servers from the same domain you can configure your webserver to act as a reverse proxy. The services (often called backend server or application server) do not necessarily need to be directly reachable from the client, it is common that only the webserver that actually serves the client ...

You're nginx configuration looks fine. I recently had the same issue as you had and had more or less the same nginx configuration. The only thing I still needed to do is to update the standalone configuration file in the keycloak folder. You can find this file at keycloak_folder/standalone/configuration/standalone.xml. Here you will have to look for the ...

Every load balancer that operates at layer seven (http) is a reverse proxy, but not every reverse proxy is a load balancer. You could say that a load balancer is a type of reverse proxy. Load balancers that work at layer four (eg AWS NLB) or below are probably also reverse proxies, but since they don't parse requests like http packets they're not as ...

By default the nginx forwards all the ( proxy_pass_request_headers on;) the header to the backend server. But if your request header ( may be custom header) includes underscore ( _ ) in the header name then nginx blocks those headers. Ex: authenticate_type, cdn_enable. To enable Nginx to pass all or the custom requested header to the backend turn on the ...

I had similar problem with web app which doesn't support samesite attribute. I've created similar workaround to @Beccari solution: proxy_cookie_path ~^/(.+)$ "/$1; SameSite=none"; You have to put it in proper context, in my case in location. If you need set up none value like in my case, please remember that you have to add Secure attribute too to enable ...

Just had a similar problem, and I only fixed it by adding the ignore_invalid_headers off also to the default server The client in my case was doing two weird (and bad-practice) things: 1) It was connecting in TLSv1.2, but without using the SNI extensions. This is used by the client to give (in cleartext) the domain name it is connecting to, so that the ...

I did some investigation on this subject. I think I found some valuable info on GitHub discussion in Yichun Zhang (author of OpenResty nginx fork) reply: I'd suggest the following options: Cache both compressed and uncompressed responses, and add (a canonical-ized) value of the Accept-Encoding to your cache key. So that clients which do not expect ...

Meanwhile I've figured it out on my own.. This is a working configuration (if anyone interested in the future): nginx_revproxy/default.conf: upstream domain1 { server wp1:80; } upstream domain2 { server wp2:80; } server { listen 80; server_name domain1.com; location / { proxy_pass http://domain1/; proxy_set_header ...

SSH client doesn't use SNI extensions of TLS protocol, which were developed to support shared hosting with HTTPS. You can try to setup your ssh client the following way: Host example.com *.example.com ProxyCommand openssl s_client -quiet -servername %h -connect example.com:2222 However I don't know if it would work. You can read more about s_client ...

You could rewrite every URI that either ends with / or does not contain a . in the last path element, before passing it to the upstream server. For example: server { ... location / { ... rewrite ^(.*)/$ $1/index.html break; rewrite ^(.*/[^./]+)$ $1/index.html break; proxy_pass ...; } } See this document for ...

Turns out there was a very simple solution to this problem after all, which we figured out after working with the Traefik vendor for a while. Turns out also that the fact that we are running Traefik in Docker does matter. The problem and solution is very specific to our setup but I still want to document here it in case others should encounter the same. ...

Just as any other web server, an HTTP reverse proxy can look at the Host header to figure out which address the client used to reach the server. This is the same mechanism that is also used by what's known as VirtualHosts. Bear in mind that with HTTPS the reverse proxy will have to terminate the TLS connection and either forward the request to the backend ...

I finally figured this out from a GitHub issue. I was trying to set both X-Forwarded-Host and the Host header and could get neither to work: From https://github.com/maptiler/tileserver-gl/issues/119 A workaround for this in IIS is to force IIS to not change the Host header. \Windows\System32\inetsrv\appcmd.exe set config -section:system.webServer/proxy -...

I solved it by creating a DNS and providing it using the server_name directive in the conf. For some reason, GCloud does not allow using the IP in the Host header, something I never had any problem using AWS services.

Services that offer dedicated IPs have exactly that: Dedicated IPs that is in use by only 1 customer. Your solutions don't offer dedicated IPs. You can proxy and tunnel all you want, but if the end result is that the email is going through your dedicated box with a single dedicated IP, the IP is no longer dedicated. (I assume your email project is multi-...

Theoretically whichever ProxyPass directive you choose, it will work, even if you choose to proxy http://example.com:8080/webapp/ as http://example.com/foo/bar/baz/. However, if your application uses absolute paths in hyperlinks, it is better to use the same URI path on both Apache and Tomcat or you will have problems like in this question. So: if your ...

The problem comes from the way you use wget. By using: wget --header="Host: example.com" http://example.com/file.html you replace the Host header of every request that wget will perform. So: wget connects to port 80 of your server and gets redirected to https://www.example.com/file.html, wget connects to port 443 of your server, but sends the Host: ...

The problem is this line: -A PREROUTING -d 40.53.XX.XX/32 -p tcp -m multiport --dports 80,443,22 -m comment --comment nginx -j DNAT --to-destination 192.168.4.2 This rule forward http (80), https (443) and ssh (22) to 192.168.4.2 host. Since your original interfaces command does not have port 22 included, port 22 must be added somewhere else to the DNAT ...

The same as most other reverse proxy set ups single point of TLS termination load balancing HA fail over only exposing the minimal ports required to the outside world

IIRC, if Cloudfront is terminating SSL, then you can't use HTTPS on the back-end and it has to be HTTP from Cloudfront<-->EC2. If you have opened that same web app/server directly to the Internet on HTTP, then that is bypassing Cloudfront and you're losing whatever caching/protection/SSL-termination/cost-savings that Cloudfront provides. You can also ...

Using HTTPS on Varnish isn't that hard. Although Varnish doesn't natively offer TLS, it facilitates TLS termination. In 2015 Varnish released Hitch, a very powerful TLS proxy that handles terminates TLS and forwards unencrypted HTTP traffic to Varnish. Installing Hitch You can download the source from the Hitch website and compile it on our server. If you ...

As both locations are on the same webserver you don't need proxy actually. You can just use location/alias for this. See these examples on how to do this: https://stackoverflow.com/questions/21399789/nginx-how-to-create-an-alias-url-route https://stackoverflow.com/questions/28490391/how-to-properly-configure-alias-directive-in-nginx Serving PHP from an ...

Nginx can certainly achieve this, but it's probably an internal rewrite you're looking for. location bar.php { rewrite . foo.php; } Nginx will check its configuration for how to run foo.php, and when that succeeds, it will seem to the user as if bar.php was run. See NStorm's answer for how to configure "location ~ .php$".

In my understanding and experience reverse_proxy takes precedence because directives have a default implicit order: https://caddyserver.com/docs/caddyfile/directives#directive-order . To force a different order you have at least 3 options: use a route: route /api/* { file_server reverse_proxy localhost:9000 } change the default order ...

You also need to pass to your old server the directories corresponding to the old site's uploaded files and theme directories. And possibly plugin directories if they serve static content or have PHP files that are called directly rather than included within WordPress. For example (uses regex, so not as efficient as it could be, but it's temporary, right?): ...

The obvious thing is that ssh is not https and its protocol does not send a hostname with which you can do matching like you can with https. I have a few hosts with similar restrictions, as they are virtual machines which don't have a global IPv4 address. For these I access them via ssh with IPv6. If for some reason you haven't deployed IPv6, you're several ...

Nginx needs to listen on port 80, which is the default for http if you don't specify a port. As in: server { listen 80; server_name xyz.zyx.de;

Certificate chain 0 s:CN = app.local.example.com i:C = US, O = Let's Encrypt, CN = Let's Encrypt Authority X3 Your server is not properly configured. Instead of sending leaf certificate (app.local.example.com) and intermediate certificate it only sends the leaf certificate. Because of the missing intermediate certificate no trust path can be created to ...

I am using nginx with PHPFPM and error was related to memory/cache as this VPS has only 1GB of RAM. First I looked into nginx logs: sudo tail /var/log/nginx/error.log -n 10 And found error: upstream sent too big header while reading response header from upstream So I added following lines in /etc/nginx/nginx.conf which fixed the issue fastcgi_buffers 16 16k; ...

Configure your backend with the correct base URL so it generates the correct links. Since you seem to be using Ghost for your blog, the option is called url. "url": "https://example.com.au/blog/" Of course it would make more sense to proxy this directly to ghost instead of proxying it twice. server { server_name example.com.au; #...
