Hello.

It's passed to fastcgi because of location / that captures uri to pass to fastcgi.

I will say, that: It's not the best solution what Igor suggest. It will get rid of the problem, but is not a real solution.

You should use:

location ~ / { try_files $uri $uri/ @framework; }

location ~ \..*/.*\.php$ { return 403; }

location ~ \.php$ { fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root/index.php; include fastcgi_params; }

You have it in debug log, in part where nginx test location. Because nginx test all you location that you have in your config, the uri with pdf file is captured by / location and proxed to fastcgi. With Igor suggestion, pdf will be added to static content location. But I will suggest, to properly configured the location that are responsible for capturing php file, because you will have a problem with all different types of files, that you don't put in that static location. like doc, xls, odt .. whatever.

BTW, it's not better (for reader, at least :} )?:

- location ~* \.css|\.js|\.jpg|\.jpeg|\.png|\.gif|\.swf|\.svg|\.tiff|\.pdf$ { + location ~* \.(css|js|jpg|jpeg|png|gif|swf|svg|tiff|pdf)$ {
