title: NSURL's parameterString confusion with use of ';' vs '&'
body: <p>I'd like to use <a href="http://developer.apple.com/mac/library/documentation/Cocoa/Reference/Foundation/Classes/NSURL_Class/Reference/Reference.html#//apple_ref/doc/uid/20000301-BAJCFFHC" rel="nofollow noreferrer"><code>-[NSURL parameterString]</code></a> to parse out the parameters of a URL I've been passed. It says URL must conform to <a href="http://www.ietf.org/rfc/rfc1808.txt" rel="nofollow noreferrer">RFC 1808</a> but now wondering if ours do?!? We use something like:</p>
  
  <p><code>http://server/path/query?property1=value1&amp;property2=value2</code>  </p>
  
  <p>but RFC 1808 never mentions the ampersand (<strong>&amp;</strong>) as a valid parameter separator (at least the way I read it). It suggests the semicolon (<strong>;</strong>). Perhaps because it was drafted in 1995? Has the <strong>&amp;</strong> replaced the <strong>;</strong>? If so anyone verify if NSURL's parameterString will also parse with &amp; as delimiter? </p>
  
  <p>What's the "right" way before we dig a big a hole?</p>
