Fixing broken Boost support for the home/root location in Nginx #104004

The updated nginx_advanced_include.conf is working fine now - thanks.

However nginx_simple_include.conf is still not working.

    ###
    ### catch all unspecified requests
    ###
    location / {
        #try_files $uri $uri/ @cache;
        if (!-e $request_filename) {
          break;
        }
        error_page 404 = @cache;
    }

The code above doesn't seem to work with the root - if you uncomment the try_files and comment the rest then it does work.

I also have noticed another problem with the @cache declaration. When boost is working it isn't setting the headers correctly.

When using simple config the http headers are:

Server: nginx/0.8.49
Date: Thu, 04 Nov 2010 12:20:37 GMT
Content-Type: text/html
Last-Modified: Wed, 03 Nov 2010 23:41:57 GMT
Vary: Accept-Encoding
Content-Encoding: gzip

200 OK

and when using advanced they are correct:

Server: nginx/0.8.49
Date: Thu, 04 Nov 2010 12:22:48 GMT
Content-Type: text/html; charset=utf-8
Last-Modified: Thu, 04 Nov 2010 11:23:06 GMT
Vary: Accept-Encoding
Expires: Tue, 24 Jan 1984 08:00:00 GMT
Cache-Control: must-revalidate, post-check=0, pre-check=0
X-Header: Boost Citrus 1.9
Content-Encoding: gzip

200 OK

I'm guessing this is down to the rewrite rule interfering with the add_header command?

        add_header Expires "Tue, 24 Jan 1984 08:00:00 GMT";        
        add_header Cache-Control "must-revalidate, post-check=0, pre-check=0";
        add_header X-Header "Boost Citrus 1.9";               
        charset utf-8;
        #try_files /cache/normal/$host${uri}_$args.html @drupal;
        if (-f $document_root/cache/normal/$host${uri}_$args.html) {
          rewrite ^/(.*)$ /cache/normal/$host${uri}_$args.html last;
          break;
        }
        error_page 404 = @drupal;

Again, when you switch back to the try_files method, it works just fine. Is there a particular reason for using the different approach in the two files?

I will be using advanced configuration myself from now on, but i noticed the default in aegir is to use the "simple" config - is there a way to change that, or is it best just to use a symlink?
