nginxUsing map

This example demonstrates redirecting old website to new and mapping old URLs to new using map rules:

map $uri $new_uri {
  default /;
  /old_article /new_article;
}

server {
  rewrite ^ https://new.com$new_uri permanent;
}ctrl + cyoutubegithub

`map` define variables map	`$uri $new_uri` will generate `$new_uri` variable value based on `$uri` and map rules
`default /;` by default `$new_uri` will contain `/` value	`/old_article /new_article` if `/old_article` request is made, `$new_uri` variable will get `/new_article` value
`server {` virtual server configuration block	`rewrite` define URL rewrite rule
`^ https://new.com$new_uri` rewrite all URLs to	`permanent` will make browser redirect instead of silent rewrite
