I have a website hosted somewhere in some server. lets say the domain name is https://www.test.com
Now, I am working on setting up the reverse proxy for this website using the upstream server for this domain name and it is not working.
I don't want to try it with the IP Address.
I want to try it upstream server with the domain name.
Any help is much appreciated.

If I have a reverse proxy server (say Nginx) running on an SSL-certified domain name, can this proxy server takes an HTTPS request and forwards it to a regular web server (say gunicorn) via HTTP without creating errors like "blocked with mixed content"?
If the answer to the above question is "no", is the only way to forward an HTTPS request from a reverse-proxy server to another regular server (hosted on some IP address) is to buy a domain name for the regular server and get it an SSL certificate?
I tried googling this but I can't find a clear answer. Any help is appreciated!
Actually, SSL termination is one of the main use cases of a reverse proxy. So yes, this is possible.
Currently I have a NGINX Reverse proxy (server A) setup that redirect all request to another server (server B).
I have an infinite number of domain name that have DNS A Record pointing to server A. Basically the Server A is a server with a static ip. So customer using my app can set up their domain name to point to server A and then the server redirect to server B is dynamic ip so that's why I have the server A.
Now what I want to achieve is that all domain pointing to server A should use HTTPS.
As my reverse proxy is not setup to accept ssl certificate, the request are blocked. I got this error while attempting to access from a domain ERR_CONNECTION_REFUSED.
The issue is, as I can have an infinite number of domain what is the best solution to make sure that all the domain can use HTTPS.
Is there a way in NGINX + Let's Encrypt to do something that would accept all domain?
Otherwise should I update and create a SSL certificate manually for each new domain and update the NGINX config?
Thank you! :)
EDIT: While manually creating the certificate on the server A it's working but I would need to figure out a way to automatically create the file ... Or find another solution.
I need to setup a reverse proxy server which would distribute traffic to the backend servers based on the incoming HOST header.
I opted for HAproxy for this but after setting up everything I realized that HAproxy reads the configuration just once when the service starts and continues to use the backend IP address unless it has been reloaded/restarted.
This is an issue for me since in my case if the backend server reboots it will have a different IP address and I dont have control on which IP address it gets.
I am thinking of moving to nginx server but before I go through all the setup I would like to know if we have the same issue with Nginx or not?
Meaning: If in the configuration file I have specific the name of backend server and if the related IP address changes, will Nginx refresh its dns cache to identify the new IP address?
(When the backend server changes IP, it is automatically updated in the hosts file of proxy server)
Yes, nginx will do the job. See 'resolve' option here:
http://nginx.org/en/docs/http/ngx_http_upstream_module.html#server
I have a domain and its DNS entries are managing using AWS Route53.
I have 30 servers on a datacenter which only have private IPs, and the sites hosted on these servers are loading using a nginx proxy server which have public IP.
For this, I have created an A record (say *.abc.com A IPofproxy), then I added some redirection rules on proxy server to load the corresponding sites.
redirection rule on proxy server are as follows :
1.abc.com redirects to 1.1.1.1
2.abc.com redirects to 2.2.2.2
3.abc.com redirects to 3.3.3.3 , etc.
But now am facing an issue with the CNAMEs,
The issue is,
I created some CNAME records like :
abc.abc.com CNAME 1.abc.com
def.abc.com CNAME 2.abc.com
fgh.abc.com CNAME 3.abc.com , etc
Then I tried to access all of the above domains (abc.abc.com , def.abc.com, etc), but all the sites are pointing to only one server which is the first one on redirection rules.
I am new to nginx, it would be great if anyone help me to fix this.
If I'm understanding your configuration correctly, the issue you're experiencing is not specifically related to either Route 53 or Nginx.
Instead, it's related to how web browsers interact with DNS entries. You'd have this issue with any reverse proxy server.
You have to configure each CNAME entry in your proxy, individually, because the browser doesn't care about the CNAME entry -- the Host: header sent with each request is the hostname the browser started with, not the hostname the browser ended up with after any CNAMEs were traversed.
a.example.com IN A 203.0.113.1
b.example.com IN CNAME a.example.com.
A request for b.example.com will be routed by the proxy according to its rules for b.example.com and not by its rules for a.example.com, because the CNAME does not change the browser's Host: header, which is what the proxy is almost certainly using for its routing decision.
If you want requests for b.example.com, it must be configured in the proxy, and not only in the DNS.
I am trying to get around ISP limitations of 1 IP address. Here is what I am trying to do. I have two web servers running internally on my network. One is my main IIS box that runs 4 or 5 sites and I just added a windows home server. I have created a dns entry for it called home.mydomain.com and the other server reponds to www.mydomain.com.
My router is set to forward 80 to www.mydomain.com's server (192.168.1.3) so when requests come in for home.mydomain.com the request fails since www server is not set up to listen to that host header.
I would like to know if there is a way with IIS 7 to 'proxy' requests to home.mydomain.com (192.168.1.4). I had tried setting up HttpRedirect in IIS but that does not work as I would have hoped since it sends back a 302 to the client with a name that points back to the main IP address and then a vicious redirect loop happens.
I am told in apache this can be done by having one server proxy for the other. Can this be done in IIS 7? If not does anyone know of a webserver proxy type of software I can use?
Thanks in advance,
Rich
What you are looking for is a "reverse proxy". In Apache you can do this via mod_proxy. In IIS, you'll want to try the Application Request Routing package.
URL Rewrite for IIS can also be used to do reverse proxing.
Yet another reverse proxy package is Managed Fusion URL Rewriter and Reverse Proxy
