title: flash: crossdomain.xml is ignored
body: <p>I have some, say, weird situation... Here is what it is:</p>
  
  <p>Flash application which records audio on one server and uploads it on another server. 
  So, as you likely guessed, I faced that security sandbox violation exceptions/errors and it seems I have to add crossdomain.xml to the root of the server. Ok, did it, but it seems it didn't get downloaded or download process is interupted, so I keep getting this errors. </p>
  
  <p>Could somebody point me to my mistakes, please? I really don't getting what I am doing wrong.  </p>
  
  <p>Here is the error I get while trying to upload audio:</p>
  
  <pre><code>Error #2044: Unhandled securityError:. text=Error #2170: Security sandbox 
  violation: https://ip1/bar/foo cannot send HTTP headers to https://ip2/foo/bar
  </code></pre>
  
  <p>Here is the content of my crossdomain.xml (test version):</p>
  
  <pre><code>&lt;?xml version="1.0"?&gt;
  &lt;!DOCTYPE cross-domain-policy SYSTEM "http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd"&gt;
  &lt;cross-domain-policy&gt;
      &lt;site-control permitted-cross-domain-policies="all"/&gt;
      &lt;allow-access-from domain="*" to-ports="*" /&gt;
      &lt;allow-http-request-headers-from domain="*" headers="*" /&gt;
  &lt;/cross-domain-policy&gt;
  </code></pre>
  
  <p>p.s. And, yes, crossdomain.xml is accessable via <code>https://ip2/crossdomain.xml</code> address.</p>
  
  <p><strong>ADDITIONAL INFO</strong>  </p>
  
  <p>I enabled flash logs and was surprised to know that flash is unable to get crossdomain.xml, though it is accessable via browser (with a clause that it is https and it states that there is a certificate issue, or smth like that).   </p>
  
  <pre><code>Warning: Failed to load policy file from https://192.168.22.103/crossdomain.xml  
  </code></pre>
  
  <p><strong>ADDITIONAL INFO PART 2</strong></p>
  
  <p>Here is the warning I have in browser in case I try to access crossdomain.xml manually:

  <p>Here is the request to download crossdomain.xml ends up with <code>http status code = 0</code>:<br>
