XF 1.4 Xenforo attachments/rewrites

[D.O.A.]

Hi, just a question for anyone out there who may know... with xenforo "pretty url's" and how the attachments are presented, does xenforo append .html to attachments during the normal course?
I know with pretty rewrites off it runs through /index.php?attachments, not sure what happens when 'on', or what handles it internally.

eg; at a log level (not in the URL)

.../attachments/1-jpg.1/index.html

I ask only as I am working on some pcre rewriting for nginx and I'm not entirely sure if it's me on the nginx end or xenforo appending that index.html. Needless to say, image URL's return a 404, so it's probably my crappy rewrite?

XenForo does not append .html onto any link.

Friendly URLs would look like:
http://www.yoursite.com/attachments/filename.1/

Non-Friendly URLs would looke like:
http://www.yoursite.com/index.php?attachments/filename.1/

Thanks for the reply, narrows it down for me... If a mod reads this perhaps it can be moved to server/troubleshooting.

I'm trying to prevent attachment hotlinking in nginx, not .jpg files the ID extensions actual attachments use. The regex seems correct, I can get things to work with pretty url's off, but not when on. (config for testing only - location security not added)

Redirect will always work but with pretty url's the image attachment itself will 404.

 server {
    listen   80;
    ...

    location / {
    try_files $uri $uri/ /index.php?$uri&$args;
    }

    location ~ \.php$ {
    ....
    }

    location ~* ([0-9a-zA-Z])+-(png|jpg|jpeg|gif)[.]([0-9]+)/$ {
    valid_referers server_names blocked *.mydomain.com;
    if ($invalid_referer) {
    rewrite ^(.*)$ url/to/goatse.gif break; #oh shi..
    }
  }
}

domain.com/attachments/someimage-jpg.3/

404's with the error;

[error] 12819#0: *7508 ".../attachments/someimage-jpg.3/index.html" is not found (2: No such file or directory), client: xxx.xxx.x.xx, server: domain.com, request: "GET /attachments/someimage-jpg.3/ HTTP/1.1", host: "domain.com", referrer: "http://domain.com/threads/sdaasd-asdada-asdadsasd-asdad.2/"

But the hotlink image with still redirect regardless, if linked elsewhere. Debug log is not helping.

edit;

Oddly enough

root ..;
index index.html index.php;
error_log ..;

Remove index.html and it becomes

.../attachments/someimage-jpg.3/index.php" is not found

From what I understand, Nginx only matches one location block per request "attempt" (try_files retries the attempt with the new URL). So basically, the try_files block isn't being hit after your referrer block... block. I don't know what the best practice is here unfortunately.
