url address rewrite

rewrite Module: rewrite instruction

sysntax : rewrite  regex replacement  [flag];

Default:   -

Context:  server,location,if

Functions:

Replace the URL specified by regex with replacement, a new URL that can use regular expressions

When the replacement begins with http: / /, https: / /, or $schema, a 302 redirect is returned directly.

The replaced url is processed according to the way specified by the flag.

last: use the replacement url to make a new location match

Break: the break instruction is to stop the execution of the current script instruction, which is equivalent to the independent break instruction.

Redirect: return 302 redirect (temporary redirect)

Persistent: returns 301 redirection (persistent redirection)
