title: Retrieve file last modified from file header using CURL
body: <p>I was wondering if it's possible to acquire the 'last modified datetime' for a csv file using CURL.</p>
  
  <p>I'm relying on a CSV file which is updated randomly to keep a database table up-to-date. I only want to update the database table with the CSV file data when the file has been modified after the last table update.</p>
  
  <p>If you know of a link to docs that describe this I would be grateful if you could post them here.</p>
  
  <p>I did some searching but my search engine was inundated with searches related to html headers.</p>
