Nginx rewrite with Simple Machines Forum

  • 772

I am running Nginx 1.5.6 and I use the Simple Machines Forum software. Most rewrite rules seem to work properly, with the exception of the RSS feeds.

In my Nginx configuration, I have the following line which is supposed to handle URLs which contain ".xml":

rewrite ^/forum/(\.xml|xmlhttp)/?$ "/forum/index.php?pretty;action=$1" last;

The above rule produces the following URL for the main forum, which returns a 403 Error: http://www.mydomain.com/forum/.xml/?type=rss

I would like the rewrite rule to produce this type of URL, which returns code 200 (a real page): http://www.mydomain.com/forum/?type=rss;action=.xml

Here is the entire block pertaining to the forum rewrites: http://pastebin.com/raw.php?i=tZkAibW3

I would really appreciate some help to create a rewrite rule to do that. Thanks.

  1. You can't include the query string in your rewrite clause (this would require a map or if). How about something like the following?

    rewrite ^/forum/rss\.xml$ /forum/index.php?pretty;action=.xml last;

    Your users could access your feed directly via http://mydomain.com/forum/rss.xml

    Well, Simple Machines is a terrible mess, but there is simply not a single good forum software out there (was always thinking about starting my own open source project for this task).

    Please try the following (correcting your evil if usage):

    server {
  location / {
    location ~ /forum/ {
      location ~ /forum/(\.xml|xmlhttp) {
        if ($args ~ type=rss) {
          rewrite ^/(.*)$ /forum/index.php?pretty;action=$1 last;
          try_files $uri @forum;
        }
      }
      try_files $uri @forum;
    }
  }
  location @forum {
