Nginx - simple permanent or temporary redirects
Temporary or permanent redirect
First you have to decide whether the redirect will be permanent (301
), or just temporary (302
). If you are uncertain, just pick temporary and switch later.
Use cases from my understanding:
- Permanent
301
redirects: - switching to another domain
- merging multiple domains
- switching from HTTP to HTTPs
- better SEO experience
- Temporary
302
redirect: - testing (A/B testing, etc)
- single redirects to another domain
- redirect to a maintenance page
- redirect traffic for load balancing
Both do the same, but still have their use cases. Switching them up could cause problems with various indexes of search engines, SEO, wrongly being flagged as a spammer, and so on.
Simple redirects in nginx
For this example, I am going to use temporary 302
redirects.
Simple redirect of a sub-domain to a single URL
server { listen 80; listen 443; server_name test2.brrl.net; location / { return 302 https://www.youtube.com/watch?v=dQw4w9WgXcQ; } }
That is a simple redirect of the root of the sub-domain. Try it out: https://test2.brrl.net.
If you want to create a redirection of a subdirectory like /status
, simply change it accordingly:
server { listen 80; listen 443; server_name brrl.net; location /status { return 302 https://status.brrl.net/status/overview; } }
With this config block, only the subdirectory /status
would be redirected. For example: https://brrl.net/status redirects to https://status.brrl.net/status/overview.
other redirects
There are many more forms of redirects, but I am familiar enough to write about that. I might add more redirects later on, but I'll have to test beforehand.
