  <title>Proposal for http Package</title>

  <div align="center">
  <h1>Proposal for <em>http</em> Package</h1>
  </div>
  
  <h3>(0) Rationale</h3>
  
  <p>Many software projects have a need to blah blah blah.  The http
  package seeks to encapsulate some  blah blah blah
  </p>
  
  
  <h3>(1) Scope of the Package</h3>
  
  <p>This proposal is to create a package of Java utility classes for
  various types of http related activity.</p>
  
  
  <h3>(1.5) Interaction With Other Packages</h3>
  
  <p><em>http</em> relies only on standard JDK 1.2 (or later) APIs for
  production deployment.  It utilizes the JUnit unit testing framework for
  developing and executing unit tests, but this is of interest only to
  developers of the component.</p>
  
  <p>No external configuration files are utilized.</p>
  
  
  <h3>(2) Initial Source of the Package</h3>
  
  <p>The original Java classes are splashed around various Apache
  subprojects.  We intend to seek them out and integrate them.</p>
  
  <p>The proposed package name for the new component is
  <code>org.apache.commons.http</code>.</p>
  
  
  <h3>(3)  Required Jakarta-Commons Resources</h3>
  
  <ul>
  <li>CVS Repository - New directory <code>http</code> in the
      <code>jakarta-commons</code> CVS repository.</li>
  <li>Mailing List - Discussions will take place on the general
      <em>commons-dev@jakarta.apache.org</em> mailing list.  To help
      list subscribers identify messages of interest, it is suggested that
      the message subject of messages about this component be prefixed with
      [http].</li>
  <li>Bugzilla - New component "http" under the "Commons" product
      category, with appropriate version identifiers as needed.</li>
  <li>Jyve FAQ - New category "commons-http" (when available).</li>
  </ul>
  
  
  <h3>(4) Initial Committers</h3>
  
  <p>The initial committers on the IO component shall be:
  <ul>
    <li>Your name here</li>
  </ul>
  </p>

  components for development and use:</p>
  <ul>
  <li><a href="http://java.sun.com/j2se">Java Development Kit</a>
      (Version 1.2 or later)</li>
  <li><a href="http://www.junit.org">JUnit Testing Framework</a>
      (Version 3.7 or later) - for unit tests only, not required
      for deployment</li>
  </ul>

   * This class parses the user agent string and sets javasciptOK and
   * cssOK following the rules described below.  If you want to check
   * for specific browsers/versions then use this class to parse the
   * user agent string and use the accessor methods in this class.
   *
   * JavaScriptOK means that the browser understands JavaScript on the
   * same level the Navigator 3 does.  Specifically, it can use named
   * images.  This allows easier rollovers.  If a browser doesn't do
   * this (Nav 2 or MSIE 3), then we just assume it can't do any
   * JavaScript.  Referencing images by load order is too hard to
   * maintain.
   *
   * CSSOK is kind of sketchy in that Nav 4 and MSIE work differently,
   * but they do seem to have most of the functionality.  MSIE 4 for the
   * Mac has buggy CSS support, so we let it do JavaScript, but no CSS.
