[Nginx] Compare rewrite last break

syntax

rewrite regex replacement [ flag ]

  • last – completes processing of current rewrite directives and restarts the process (including rewriting) with a search for a match on the URI from all available locations.
  • break – completes processing of current rewrite directives and non-rewrite processing continues within the current location block only.
  • redirect – returns temporary redirect with code 302; it is used if the substituting line begins with http:// (デフォルト)
  • permanent – returns permanent redirect with code 301
