title: Cookie problems with virtual directories in IIS (deleting unwanted cookies)
body: <p>I've just had a small nightmare with unwanted cookies somehow being created. I swear my code never created a cookie in a certain virtual directory, it just read it, but somehow my browser ended up with a root cookie and a copy of this cookie for the vdir too. Which meant the two values were separate and did not both get updated.</p>
  
  <p>Most articles about deleting cookies say to set it to blank, which is no help, as it will still exist!</p>
  
  <p>I had to write a short ASP to set the cookie expiry to last year, and also make sure I specified the path as the vdir in question, to make sure it killed the one I didn't want.</p>
  
  <pre><code>Response.Cookies("BWWF2")("UID") = ""
  Response.Cookies("BWWF2").Path = "/community"
  Response.Cookies("BWWF2").Expires = DateAdd("yyyy", -1, Now())
  </code></pre>
  
  <p>Hopefully this has solved the problem, but I wanted to share this here, and also ask if anyone has a better way to solve the issue, or any ideas on how the problem (two cookies) might have happened in the first place?!</p>
