title: Stopping invalid file type or file name submissions in coldfusion
body: <p>So, I'm having this lovely issue where people like to submit invalid file types or funky named files... (like.. <code>hey_i_like_"quotes".docx</code>) Sometimes they will even try to upload a .html link...</p>
  
  <p>How should I check for something like this? It seems to create an error every time someone submits a poorly named item.</p>
  
  <p>Should I create a cfscript that checks it before submission? Or is there an easier way?</p>
