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: October 1 5, 2010</td>437 <td class="left">Expires: October 18, 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">April 1 3, 2010</td>490 <td class="right">April 16, 2010</td> 491 491 </tr> 492 492 </tbody> … … 516 516 in progress”. 517 517 </p> 518 <p>This Internet-Draft will expire in October 1 5, 2010.</p>518 <p>This Internet-Draft will expire in October 18, 2010.</p> 519 519 <h1><a id="rfc.copyrightnotice" href="#rfc.copyrightnotice">Copyright Notice</a></h1> 520 520 <p>Copyright © 2010 IETF Trust and the persons identified as the document authors.
