title: How long can a hyperlink be?
body: <p>On my website, an user can insert a hyperlink in a text input field.  Then, this link (a string) is stored in my database.</p>
  
  <p>On MySQL, the field that contains the hyperlink string is <code>TEXT</code> type, but I think its too long for this kind of information.  Besides, <code>VARCHAR(255)</code> is too short sometimes. </p>
  
  <p>What's the best type/length to store a hyperlink?  It would be nice to know how long a link can be.</p>
