I'm using nginx as a frontend to Rails. All pages are cached as .html
files on disk, and nginx serves these files if they exist. I want to send the correct MIME type for feeds (application/rss+xml
), but the way I have so far is quite ugly, and I'm wondering if there is a cleaner way.
Here is my config:
location ~ /feed/$ {
types {}
default_type application/rss+xml;
root /var/www/cache/;
if (-f request_filename/index.html) {
rewrite (.*) $1/index.html break;
}
if (-f request_filename.html) {
rewrite (.*) $1.html break;
}
if (-f request_filename) {
break;
}
if (!-f request_filename) {
proxy_pass http://mongrel;
break;
}
}
location / {
root /var/www/cache/;
if (-f request_filename/index.html) {
rewrite (.*) $1/index.html break;
}
if (-f request_filename.html) {
rewrite (.*) $1.html break;
}
if (-f request_filename) {
break;
}
if (!-f request_filename) {
proxy_pass http://mongrel;
break;
}
}
My questions:
- Is there a better way to change the MIME type? All cached files have
.html
extensions and I cannot change this. - Is there a way to factor out the
if
conditions in/feed/$
and/
? I understand that I can useinclude
, but I'm hoping for a better way. Putting part of the config in a different file is not that readable. - Can you spot any bugs in the
if
conditions?
I'm using nginx 0.6.32 (Debian Lenny). I prefer to use the version in APT.
Thanks.
