DESCRIPTION
       The QHttpHeader class contains header information for HTTP.

       In most cases you should use the more specialized derivatives of this
       class, QHttpResponseHeader and QHttpRequestHeader, rather than directly
       using QHttpHeader.

       QHttpHeader provides the HTTP header fields. A HTTP header field
       consists of a name followed by a colon, a single space, and the field
       value. (See RFC 1945.) Field names are case-insensitive. A typical
       header field looks like this:

	   content-type: text/html

       In the API the header field name is called the "key" and the content is
       called the "value". You can get and set a header field's value by using
       its key with value() and setValue(), e.g.

	   header.setValue( "content-type", "text/html" );
	   QString contentType = header.value( "content-type" );

       Some fields are so common that getters and setters are provided for
       them as a convenient alternative to using value() and setValue(), e.g.
       contentLength() and contentType(), setContentLength() and
       setContentType().

       Each header key has a single value associated with it. If you set the
       value for a key which already exists the previous value will be
       discarded.

       See also QHttpRequestHeader, QHttpResponseHeader, and Input/Output and
       Networking.

MEMBER FUNCTION DOCUMENTATION
QHttpHeader::QHttpHeader ()
       Constructs an empty HTTP header.

QHttpHeader::QHttpHeader ( const QHttpHeader & header )
       Constructs a copy of header.

QHttpHeader::QHttpHeader ( const QString & str )
       Constructs a HTTP header for str.

       This constructor parses the string str for header fields and adds this
       information. The str should consist of one or more" \r\n" delimited
       lines; each of these lines should have the format key, colon, space,
       value.

QHttpHeader::~QHttpHeader () [virtual]
       Destructor.

uint QHttpHeader::contentLength () const
       Returns the value of the special HTTP header field content-length.

       See also setContentLength() and hasContentLength().

QString QHttpHeader::contentType () const
       Returns the value of the special HTTP header field content-type.

       See also setContentType() and hasContentType().

bool QHttpHeader::hasContentLength () const
       Returns TRUE if the header has an entry for the special HTTP header
       field content-length; otherwise returns FALSE.

       See also contentLength() and setContentLength().

bool QHttpHeader::hasContentType () const
       Returns TRUE if the header has an entry for the the special HTTP header
       field content-type; otherwise returns FALSE.

       See also contentType() and setContentType().

bool QHttpHeader::hasKey ( const QString & key ) const
       Returns TRUE if the HTTP header has an entry with the given key;
       otherwise returns FALSE.

       See also value(), setValue(), and keys().

bool QHttpHeader::isValid () const
       Returns TRUE if the HTTP header is valid; otherwise returns FALSE.

       A QHttpHeader is invalid if it was created by parsing a malformed
       string.

QStringList QHttpHeader::keys () const
       Returns a list of the keys in the HTTP header.

       See also hasKey().

int QHttpHeader::majorVersion () const [pure virtual]
       Returns the major protocol-version of the HTTP header.

       Reimplemented in QHttpResponseHeader and QHttpRequestHeader.

int QHttpHeader::minorVersion () const [pure virtual]
       Returns the minor protocol-version of the HTTP header.

       Reimplemented in QHttpResponseHeader and QHttpRequestHeader.

QHttpHeader & QHttpHeader::operator= ( const QHttpHeader & h )
       Assigns h and returns a reference to this http header.

void QHttpHeader::removeValue ( const QString & key )
       Removes the entry with the key key from the HTTP header.

       See also value() and setValue().

void QHttpHeader::setContentLength ( int len )
       Sets the value of the special HTTP header field content-length to len.

       See also contentLength() and hasContentLength().

void QHttpHeader::setContentType ( const QString & type )
       Sets the value of the special HTTP header field content-type to type.

       See also contentType() and hasContentType().

       Example: network/archivesearch/archivedialog.ui.h.

void QHttpHeader::setValue ( const QString & key, const QString & value )
       Sets the value of the entry with the key to value.

       If no entry with key exists, a new entry with the given key and value
       is created. If an entry with the key already exists, its value is
       discarded and replaced with the given value.

       See also value(), hasKey(), and removeValue().

       Example: network/archivesearch/archivedialog.ui.h.

QString QHttpHeader::toString () const [virtual]
       Returns a string representation of the HTTP header.

       The string is suitable for use by the constructor that takes a QString.
       It consists of lines with the format: key, colon, space, value, "\r\n".

QString QHttpHeader::value ( const QString & key ) const
       Returns the value for the entry with the given key. If no entry has
       this key, an empty string is returned.

       See also setValue(), removeValue(), hasKey(), and keys().
