If you need to duplicate more than a few redirects, you might consider using a map:
# map is outside of server block
map $uri $redirect_uri {
~^/issue1/?$ http://example.com/shop/issues/custom_isse_name1;
~^/issue2/?$ http://example.com/shop/issues/custom_isse_name2;
~^/issue3/?$ http://example.com/shop/issues/custom_isse_name3;
# ... or put these in an included file
}
location / {
try_files $uri $uri/ @redirect-map;
}
location @redirect-map {
if ($redirect_uri) { # redirect if the variable is defined
return 301 $redirect_uri;
}
}
