Method Detail

parseStatusLine

public static StatusLine parseStatusLine(java.lang.String line)
                                  throws HttpParser.ParseException

Parse a HTTP response status line.

Parameters:

line - to parse

Returns:

the StatusLine

Throws:

HttpParser.ParseException - if the line cannot be parsed or has the wrong HTTP version

getAuthenticationHeaders

public static java.util.List<AuthenticationChallenge> getAuthenticationHeaders(java.util.List<java.lang.String> reply,
                                                                               java.lang.String authenticationHeader)

Extract the authentication headers from the header lines. It is assumed that the first element in reply is the raw status line as received from the server. It is skipped. Line processing stops on the first empty line thereafter.

Parameters:

reply - The complete (header) lines of the HTTP response

authenticationHeader - to look for (including the terminating ':'!)

Returns:

a list of AuthenticationChallenges found.

parseChallenges

private static void parseChallenges(java.util.List<AuthenticationChallenge> challenges,
                                    java.lang.String header)

parseChallenge

private static int parseChallenge(AuthenticationChallenge challenge,
                                  java.lang.String header,
                                  int from)

skipWhiteSpace

private static int skipWhiteSpace(java.lang.String header,
                                  int i)

scanQuotedString

private static java.lang.String scanQuotedString(java.lang.String header,
                                                 int from,
