Hello,

I'm trying to use the nginx plugin web interface to create a redirect from non-www to www domains. I might be missing it, but there doesn't seem to be any options to allow me to redirect a domain in either the http server or location. Nothing fancy, just a return 301 (new url);.

Another option I can do is generate the config files directly on disk, since the plugin has facilities to plop your own nginx server blocks but i hesitate to go that route since nginx currently manages generating the SSL blocks for my HTTPS servers, I'm concerned about keeping the two in sync (the web ui vs the manually generated redirect server blocks).

Does anyone know of a way to have nginx generate http redirects for domains?

Any input here?

URL Rewrite is not appropriate?
see screenshot.

I naively thought that was specific for paths. Didn't even consider it might work for domains. I'll try it out.

If you separate the hosts, it will very likely work.

Hi,

I finally got around to trying it, and I don't believe it works, at least not as I need it.

Going through the UI then looking at the generated nginx.conf, I see a

> rewrite example.com https://www.example.com permanent;

However the browser doesn't get redirected. Not does the content show up for what would be under www.example.com

Ideally, what I need is more akin to return 301 https //www.example.com$request_uri, so an http 301 redirect.

Example:

Regex: (.*)
New URL Pattern: https://fabian-franz.eu$1
Flag: Redirect

Result:

Code Select

curl -v "http://fw.test/test.txt"
> GET /test.txt HTTP/1.1
> Host: fw.test
> User-Agent: curl/7.64.1
> Accept: */*
>

Hello Fabian,

is there a chance to get a real redirect - not a rewrite?

If I use "permanent" I get:
Code Select
rewrite / https://server.name permanent;

If I use "redirect" I get:
Code Select
rewrite / https://server.name redirect;

What I need is:
Code Select
return 301 https://server.name;

At least that is the only option that worked for me. I added it manually, but I guess with next reboot, latest with next config change, it will be reverted to a rewrite.

301 works using permanent:

https://nginx.org/en/docs/http/ngx_http_rewrite_module.html#rewrite

rewrite is just the name of the nginx directive.

Ah! I think I did it completely wrong then. I was trying to capture on the domain (example.com) to redirect to www.example.com but it makes sense to capture (.*) on the example..com server and do the redirect to www.example.com

I will try that! Thank you.
