title: zero size shared memory zone "proxied" in nginx
body: <p>I installed nginx  with nginx-extras  to get (Http Upload Progress Module).</p>
  
  <p>Then i tried to use it following this documentation ( example on the bottom of the page ) -> <a href="http://wiki.nginx.org/HttpUploadProgressModule" rel="nofollow">http://wiki.nginx.org/HttpUploadProgressModule</a>. After inserting this one line (<code>track_uploads proxied 30s;</code>) in my configuration , i get the following error </p>
  
  <blockquote>
    <p>nginx: [emerg] zero size shared memory zone "proxied"</p>
  </blockquote>
  
  <p>Somewhere on the internet i found , that someone suggested to insert <code>upload_progress proxied 10m;</code> into nginx.conf , and after inserting it i started geting the following error:</p>
  
  <blockquote>
    <p>nginx: [emerg] the size 10485760 of shared memory zone "proxied"
    conflicts with already declared size 0 in /etc/nginx/nginx.conf:75</p>
  </blockquote>
  
  <p>This the part of the config , where are inserted this line....</p>
  
  <pre><code> location ~ \.php$ {
    include /etc/nginx/fastcgi_params;
    fastcgi_pass 127.0.0.1:9000;
    fastcgi_param SCRIPT_FILENAME /home/cha0s/learnphp$fastcgi_script_name;
    fastcgi_param PATH_INFO $fastcgi_script_name;
  
    track_uploads proxied 1m;
  }
  </code></pre>
  
  <p><strong>So the question is , what should i write in nginx.conf  to resolve this error ? Thanks in advance.</strong> </p>
