I'm seeing gibberish or weird encoding errors in HTML parsed by mod_cdn.

This might be due to interactions between mod_cdn and another Apache module. Some users have reported problems with mod_deflate in some versions of Apache, although we've used mod_cdn and mod_deflate together successfully with Apache 2.2.8. Try temporarily disabling unnecessary modules. If that fixes your problem, please let us know the details of your situation and we'll try to address the problem permanently.

How do I set up mod_cdn on CentOS/Fedora/Redhat?

The installation instructions above are for Debian systems. Everything is mostly the same on a CentOS system, except for the layout of the Apache configuration. Take the lines from cdn.load and put them in /etc/httpd/conf/httpd.conf near the other LoadModule lines. (Don't forget to make sure that libxml2 is installed and available at /usr/lib/libxml2.so.2; if it's available elsewhere, change the LoadFile line.) Put cdn.conf in /etc/httpd/conf.d....read more

How do I compile mod_cdn?

Currently there are no packages for mod_cdn, although we're in the process of making some for, at least, Debian and CentOS. That means you need to compile mod_cdn from the source. To do this, you need to install APR, the Apache runtime library. On a Debian system, the package is libapr1-dev; you may also need libaprutil1-dev. You should compile mod_cdn against Apache 2.2.7 or higher. (Our testing has mainly been with 2.2.8.) Then, just run make.

VoxCAST Auth Token Example

 
function make_signed_url($complete_url, $key, $expire_seconds)
{
  // Separate the query parameters from the base URL
  $exploded_url = explode('?', $complete_url, 2);

  $base_url = $exploded_url[0];
  $qparams = array();

  // create an array of the query parameter key/value pairs
  if(isset($exploded_url[1]) && !empty($exploded_url[1]))
  {
    $params = explode('&', $exploded_url[1]);
    foreach($params as $param)

Email Sending from VoxSTRUCTURE Servers

Voxel's on-demand infrastructure, including automatically deployed VoxCLOUD and VoxSERVER servers, come with a default ACL that blocks outbound email. Although Voxel firmly believes in providing our customers with unrestricted access to all Internet destinations, the sending of spam through mass-emailing or exploited software is a major concern for cloud-based infrastructure.  As such, Voxel provides a free, easy-to-use SMTP service for our VoxSTRUCTURE customers....read more
