title: Converting blob back to original file type and making it available for download
body: <p>So I have a client application built using HTML5 and JavaScript. My application invokes a web service (built using c#), which extracts a blob data from a MySql database and passes it on to the client application.</p>
  <p>This blob data is actually a small file (less than 100kb) which was stored in the MySQL Database. I want my client application to be able to convert this blob back to its original file type and then ask the user for download permissions. Now I was wondering if this is a good idea or not? Or should I simply do the file conversion in my Web Service and then send the file itself to the JSP application?</p>
  <p>Any help / suggestions will be highly appreciated! And if you have any good tutorials / codes, which might help me with the conversion then please post them here as an answer? Thanks in advance!</p>
