I'm using Nginx 0.7.64, Passenger 2.2.9, Rails 2.3.5. I have my page caching directory set to /public/cache, and I'd like to be able to serve cached pages when requested over HTTP, but always hit the Rails app when requested over HTTPS.
The bulk of my config looks like this:
server {
listen 80;
server_name website.com www.website.com;
proxy_set_header X-Forwarded-Proto http;
root /home/deploy/website/current/public;
passenger_enabled on;
if (-f $document_root/cache/$request_filename.html) {
rewrite (.*) $document_root/cache/$1.html break;
}
}
server {
listen 443;
server_name website.com www.website.com;
root /home/deploy/website/current/public;
passenger_enabled on;
proxy_set_header X-Forwarded-Proto https;
ssl on;
ssl_certificate /home/deploy/website/shared/ssl/www.website.com.combined.crt;
ssl_certificate_key /home/deploy/website/shared/ssl/www.website.com.key;
}
I anticipate that when I request website.com/about, I should be served /public/cache/about.html, but instead I hit the Rails server (tailing the log shows it).
Thinking I might have an inappropriate slash (and not seeing $document_root
in most examples), I've also tried all of the following variations, none of which work:
if (-f cache$request_filename.html) {
rewrite (.*) cache$1.html break;
}
if (-f /cache$request_filename.html) {
rewrite (.*) /cache$1.html break;
}
if (-f cache/$request_filename.html) {
rewrite (.*) cache/$1.html break;
}
if (-f /cache/$request_filename.html) {
rewrite (.*) /cache/$1.html break;
}
I've also thrown the root
, passenger_enabled
, and rewrite rules into a separate location /
block, but that also does not work. I've also reordered the statements so that passenger_enabled
would come at the end. I've also tried using $uri
. Clearly I'm misunderstanding something!
This is a little bit simplified, since I also have an XML api that is cached in places (presumably the rewrite rule will be the same except for the .html
parts), as well as I'll need to serve public/cache/index.html
when the root of website.com
is requested. I just want to get any single piece of it working. :)
Any help is appreciated!
Update
The conditional
if (-f $document_root/cache$request_uri.html)
Seems to work! However, what I would think would be the rewrite does not work! Trying
if (-f $document_root/cache$request_uri.html) {
rewrite (.*) /cache$1.html break;
break;
}
Rewrites the URL as /cache/cache/about.html.html
and sends it to Rails, which promptly barfs. It looks doubled, yes! But if I rewrite to just /cache$1
it sends /cache/cache/about
to Rails, and $1.html
sends /about.html.html
to Rails, and just $1
sends simply /about
which goes to Rails and does not hit the cache. Obviously this is not correct behavior Is Nginx rewriting it and then Passenger is rewriting it, too?
