- public class HttpParser 
- extends java.lang.Object
HTTP header value parser implementation. Parsing HTTP headers as per RFC2616
 is not always as simple as it first appears. For headers that only use tokens
 the simple approach will normally be sufficient. However, for the other
 headers, while simple code meets 99.9% of cases, there are often some edge
 cases that make things far more complicated.
 The purpose of this parser is to let the parser worry about the edge cases.
 It provides tolerant (where safe to do so) parsing of HTTP header values
 assuming that wrapped header lines have already been unwrapped. (The Tomcat
 header processing code does the unwrapping.)
 Provides parsing of the following HTTP header values as per RFC 2616:
 - Authorization for DIGEST authentication
 - MediaType (used for Content-Type header)
 Support for additional headers will be provided as required.

- Parses an HTTP Authorization header for DIGEST authentication as per RFC
 2617 section 3.2.2.
 
- 
- Parameters:
- input- The header value to parse
- Returns:
- A map of directives and values as Strings ornullif a parsing error occurs. Although the
          values returned areStrings they will have been
          validated to ensure that they conform to RFC 2617.
- Throws:
- java.lang.IllegalArgumentException- If the header does not conform to RFC
                                  2617
- java.io.IOException- If an error occurs while reading the input
