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."> … … 436 436 </tr> 437 437 <tr> 438 <td class="header left">Expires: February 2 5, 2010</td>438 <td class="header left">Expires: February 28, 2010</td> 439 439 <td class="header right">H.
