title: How can you check if a file is stored in Azure Blob
body: <p>We have a flash app running on our web site (which is a Azure site).  It needs to access images in blob storage.  I had to create a crossdomain.xml file programatically so there won't be any issues with Flash getting cross domain restrictions.</p>
  
  <p>But for some reason, I cannot check to see if that file exists, so every time the page loads it re-creates the file.  Every example I look for talks about checking to see if the blob storage container exists, I just want to find this file.</p>
