NginxHttpMapModule

Server NGINX
1

I’m unclear how to mimic the Apache rewrite map using the
NginxHttpMapModule.

I’ve included a map in my nginx.conf file, as so:

===================================
map $uri $new {
default http://www.domain.com/home/;

/aa http://aa.domain.com/;
/bb http://bb.domain.com/;
/john http://my.domain.com/users/john/;
}

Then have trouble using the map without excuding all other rules in my
server configuration. The following rewrites everything, obviously, but
couldn’t figure out how to get a conditional match wrapped around it or
from it:

===================================
server {
listen 80;
server_name some.domain.com;
rewrite ^ $new redirect;

root /var/www/web;
index index.php;

access_log /var/log/httpd/nginx_access_log main;
error_log /var/log/httpd/nginx_error_log;

charset utf-8;

location / {

# If the file exists as a static file serve it directly without
# running all the other rewite tests on it
if (-f $request_filename) {
  expires max;
  break;
}

if ($request_filename !~ "\.(js|htc|ico|gif|jpg|png|css)$") {
  rewrite ^(.*) /index.html last;
}

}

I’m obviously missing something, but how would one wrap this Map
conditionally? If no “map” rules trigger, continue with "locations’…

Is this possible?

Thanks in advance!

To follow up, it’s really simple. You don’t need the Map module, just a
text file with rewrite directives, and the include directive.

Doh! Not sure why I went the confusing route…

location / {

include /path/to/rewrite_rules_x.txt;

+++++++++++++++++++++++++++++++

cat /path/to/rewrite_rules_x.txt

rewrite /aaa /someotherpage;
rewrite /bbb http://forum.nginx.org;
…

No, it’s better to use this configuration:

map $uri $new {
default “”;

/aa http://aa.domain.com/;
/bb http://bb.domain.com/;
/john http://my.domain.com/users/john/;
}

server {

if ($new) {
    rewrite  ^  $new;
}

...
