Part 1 provides an overview of HTTP and its associated terminology, defines the "http" and "https" Uniform Resource Identifier (URI) schemes, defines the generic message syntax and parsing requirements for HTTP message frames, and describes general security concerns for implementations."> … … 435 435 </tr> 436 436 <tr> 437 <td class="left">Expires: July 5, 2010</td>437 <td class="left">Expires: July 12, 2010</td> 438 438 <td class="right">HP</td> 439 439 </tr> … … 488 488 <tr> 489 489 <td class="left"></td> 490 <td class="right">January 1, 2010</td>490 <td class="right">January 8, 2010</td> 491 491 </tr> 492 492 </tbody> … … 520 520 <p>The list of Internet-Draft Shadow Directories can be accessed at <<a href="http://www.ietf.org/shadow.html">http://www.ietf.org/shadow.html</a>>. 521 521 </p> 522 <p>This Internet-Draft will expire in July 5, 2010.</p>522 <p>This Internet-Draft will expire in July 12, 2010.</p> 523 523 <h1><a id="rfc.copyrightnotice" href="#rfc.copyrightnotice">Copyright Notice</a></h1> 524 524 <p>Copyright © 2010 IETF Trust and the persons identified as the document authors.
