If you run nginx behind a CDN, you will by default see the proxy/CDNIPinstead of the real client. Edit the global http { part of nginx.conf and add this: # 1. Specify the IP address of your trusted proxy/load balancer set_real_ip_from 1.2.3.4; set_real_ip_from 5.2.3.4; # 2. Specify which header contains the real client IP real_ip_header X-Forwarded-For;........

The client needs a new connection for this request as the requested host name does not match the Server Name Indication (SNI) in use for this connection. Before reading this, I assume you've done all the proper troubleshooting and you are 100% sure the CDN and backend server is configured correctly. This can often happen........

Add this to your Apache config: LoadModule log_forensic_module modules/mod_log_forensic.so Restart Apache Set the location of the forensic log. ForensicLog /var/log/apache2/forensic.log Here is an example of an entry in forensic: +16831:68ca525e:3c5|GET /some/url HTTP/1.1|sec-fetch-dest:document|user-agent:Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15........

This solves the problem where your logs and services will only see the proxy/CDN IP and not the real client IP. modremoteip is the most modern and current working solution Step 1.) Enable remoteip a2enmod remoteip Step 2.) Edit/Enable the correct config Edit t........

You can find it for free at http://nginx.org/ I find nginx is simpler to setup than pound (it's not hard but I found it unintuitive and annoying), it seemed to make some basic setups overly complicated with the config file syntax. nginx on the other hand is perfectly suited in everyway, it is even simpler to setup and seems to be the most stable and most efficient any load balancer. I would go as far as to say that a good nginx setup is more relia........

I have played around with Pound a little bit. It is a reverse proxy and load balancer in one, and it can be used as only a reverse proxy if you like. It is very simple to configure as either, and Pound even senses if one of the systems is down and stops sending requests to the dead server. It supports SSL (but passes the request to the destination server unencrypted) and even the Apache log format. Pound is very simple, fast a........
