Nginx redirect loop re write as a logarithmic equation

It is capable of handling a huge number of concurrent connections easily see the C10K problem. Over a year ago, I wrote about using nginx as a load balancer and remote proxy.

Since then, my understanding of nginx and best practices in its configuration have progressed significantly. This makes it an excellent choice as a load balancer and reverse proxy. Nginx running on a single server handles incoming client requests and distributes them to a pool of upstream application servers that actually fulfill the requests.

The pool of application servers can be easily scaled up or down to handle changes in traffic levels. This flexibility provides a way to scale the capacity of almost any web application quite easily. Following are some specific scenarios and nginx configuration examples that I have used when setting up and maintaining applications and network infrastructures for both Atomic Object and our clients.

We have a JRuby application running on Apache Tomcat. The application gets a significant amount of traffic and is no longer performing as well as required. Instead, we decide to scale horizontally and add more servers.

First, we setup a new nginx server to a accept the connections, and distribute them to our Tomcat application servers. We set nginx to listen on port If it does, it serves it.

Otherwise, it continues down the list of checks so see if the request can be handled locally. If the request cannot be served locally, nginx passes it to the proxy location block, which will proxy the request to the upstream JRuby applications running on port This is extremely powerful as it allows nginx to intercept certain requests before they are proxied to upstream applications.

This is useful for static assets such as images and files. Additionally, the check for a maintenance page allows us to selectively put the entire site in maintenance mode simply by creating a file.

Our new cluster of servers has been running great. Instead, all clients have an IP address of Fortunately, all that we need to do is to tell nginx to set or pass on certain HTTP headers to the upstream JRuby application.

In addition, we can set certain headers based on characteristics of the client connection. In this instance, X-Real-IP is set to the remote address of the client. Our JRuby application now needs to be able to secure client requests. In our current setup, all connections to upstream JRuby application servers are on a private network, and so do not need to be separately secured.

Nginx does not have a separate directive for providing a SSL chain certificate such as with Apache HTTPso any chain certificates need to be appended to the primary certificate e. This tends to be for non-public-facing websites such as particular client application instances.

While it would be better that the connections were originally made with SSL, we can provide a redirect as a convenience to users where appropriate. Note that the server block for port 80 has no means of actually proxying the request.The only thing that could be a concern are- the rewrite rules.

[space] What are rewrite rules? In simple terms, rewrite rules allow you to have pretty permalinks.

Essentially they are rules added, similar to formulas, which resolve the URL structure and redirect to the associated page. You need to exclude it to prevent a loop. Try: rewrite ^(/[^/]+)$ $1/system redirect; See this useful resource on regular expressions.

https redirect going to infinite loop. Hi, I am new to nginx. I am trying to redirect all request to https. This is the redirect i am using rewrite ^/.*) When you redirect one URL to another —this should be a linear flow.
