nginx url rewrite with string substitution

Question

I need to catch if my urls contain a small substr, keep the url as it is and rewrite only that small part, how can I accomplish this?

For example:

http://foobar.com/foo-bar-substrtocatch-baz

should become

http://foobar.com/foo-bar-changedsubstr-baz

Thanks in advance...

Wouldn't `return` be better to inform SEO and robots of the 301? – Zac Grierson Jul 03 '17 at 21:35

@ZacGrierson It depends on what you want to do; if a 301 is required, just use the `permanent` flag as per http://nginx.org/r/rewrite – cnst Jul 05 '17 at 03:41
