My original setup was to read an HTTP cookie set by some application and depending on its value, direct the reverse proxy to different backends. It went something like this:. But it didn't.
And now I can see that the if block gets activated, but instead of proxying the request like I thought it would do it returns a redirect to the URL specified - which is not what I'm trying to do: I need the server to transparently relay the request to the backends and pipe the response to the original client.
Similar to this answer. Nginx's idiomatic approach to this kind of problems is via map. The test is done in the server scope for each request before the actual redirect is resolved and is just used to set a variable - this is apparently a supported usage of Nginx "rewrite" module. Then in the location scope where I want to do the redirect, I use the variable name that either contains the default upstream configuration or was overwritten by the cookie.

Thanks, that's a better approach then mine, most notably because I can use the named cookie variable directly not sure why I can't in if and I implemented it. There is one issue though - Nginx at least my version: 1. I've edited your answer accordingly. That indeed worked for the test, though I'm not sure why I can't just test against the specific cookie name.
I have updated the question accordingly. Which version of Nginx are you using? I'm using 1. The solution in the forum is to not change the request URI when proxying to another server, but that is exactly what I need to do - rewrite the request URI to target an application different then what the original URL includes.

When websites are full of images and interactive content run by scripts loaded in the background, opening a website is not a simple task. It consists of requesting many different files from the server one by one. Minimizing the quantity of these requests is one way to speed up your website.
This can be done in many ways, but one of the more important steps to take is to configure browser caching.Catholic retreats in louisiana
This is telling the browser that files downloaded once can be reused from local copies instead of requesting the server for them again and again. To do this, new HTTP response headers telling the browser how to behave must be introduced. This module can be used to add any arbitrary headers to the response, but its major role is to properly set caching headers. One Ubuntu In this step, we will create several test files in the default Nginx directory. To make a decision about what kind of file is served over the network, Nginx does not analyze the file contents; that would be prohibitively slow.
How to Implement Browser Caching with Nginx's header Module on Ubuntu 16.04
Because of this behavior, the content of our test files is irrelevant. By naming the files appropriately, we can trick Nginx into thinking that, for example, one entirely empty file is an image and another is a stylesheet. Create a file named test. The next step is to check how Nginx behaves with respect to sending caching control headers on a fresh installation with the files we have just created.
By default, all files will have the same default caching behavior. The following command requests a file from our local Nginx server and shows the response headers. In the second to last line you can see the ETag header, which contains a unique identifier for this particular revision of the requested file.
If you execute the previous curl command repeatedly, you will see the exact same ETag value. When using a web browser, the ETag value is stored and sent back to the server with the If-None-Match request header when the browser wants to request the same file again — for example, when refreshing the page. We can simulate this on the command line with the following command. Make sure you change the ETag value in this command to match the ETag value in your previous output.ConfigMaps allow you to decouple configuration artifacts from image content to keep containerized applications portable.
The data provides the configurations for system components for the nginx-controller. In order to overwrite nginx-controller configuration values as seen in config. For Example:. The key and values in a ConfigMap can only be strings.
