I'm trying to save the output of a fastcgi, but I seem to be getting a blank output.
If a user requests a file like /thumbnail/someuniquefilename.jpg and the file exists, it should just serve it. If it doesn't exist, it should fetch it via fastcgi with custom GET query string. So, I have something like this as of now:
location ~ ^/thumbnail/ {
root /var/www/html;
expires 24h;
error_page 404 = @fetchthumbnail;
}
location @fetchthumbnail {
fastcgi_pass php;
fastcgi_store on;
fastcgi_store_access user:rw group:rw all:r;
fastcgi_temp_path /var/www/temp;
fastcgi_param SCRIPT_NAME /var/www/html/thumbnailer.php;
fastcgi_param QUERY_STRING src=/actual/path/$request_filename;
}
But I seem to be getting a blank page as a result.

I've made some additional tests. And it appears the thumbnailer.php is not actually being run. Thus, the blank response.
Error logs only shows that thumbnail/someuniquefilename.jpg wasn't found since it really doesn't exist (or deleted after trial).
