    • encodeBasicAuthentication

      public static String encodeBasicAuthentication(String pUser, String pPassword, String pEncoding) throws UnsupportedEncodingException
      Creates the Base64 encoded credentials for HTTP Basic Authentication.
      Parameters:
      pUser - User name, or null, if no Basic Authentication is being used.
      pPassword - Users password, or null, if no Basic Authentication is being used.
      pEncoding - Encoding being used for conversion of the credential string into a byte array.
      Returns:
      Base64 encoded credentials, for use in the HTTP header
      Throws:
      UnsupportedEncodingException - The encoding pEncoding is invalid.
    • isUsingGzipEncoding

      public static boolean isUsingGzipEncoding(String pHeaderValue)
      Returns, whether the HTTP header value pHeaderValue indicates, that GZIP encoding is used or may be used.
      Parameters:
      pHeaderValue - The HTTP header value being parsed. This is typically the value of "Content-Encoding", or "Accept-Encoding".
      Returns:
      True, if the header value suggests that GZIP encoding is or may be used.
    • getNonIdentityTransferEncoding

      public static String getNonIdentityTransferEncoding(String pHeaderValue)
      Returns, whether the HTTP header value pHeaderValue indicates, that another encoding than "identity" is used. This is typically the value of "Transfer-Encoding", or "TE".
      Returns:
      Null, if the transfer encoding in use is "identity". Otherwise, another transfer encoding.
    • isUsingGzipEncoding

      public static boolean isUsingGzipEncoding(Enumeration pValues)
      Returns, whether the HTTP header values in pValues indicate, that GZIP encoding is used or may be used.
      Parameters:
      pValues - The HTTP header values being parsed. These are typically the values of "Content-Encoding", or "Accept-Encoding".
      Returns:
      True, if the header values suggests that GZIP encoding is or may be used.
    • readLine

      public static String readLine(InputStream pIn, byte[] pBuffer) throws IOException
      Reads a header line from the input stream pIn and converts it into a string.
      Parameters:
      pIn - The input stream being read.
      pBuffer - A buffer being used for temporary storage. The buffers length is a limit of the header lines length.
      Returns:
      Next header line or null, if no more header lines are available.
      Throws:
      IOException - Reading the header line failed.
    • parseAuthorization

      public static void parseAuthorization(XmlRpcHttpRequestConfigImpl pConfig, String pLine)
      Parses an "Authorization" header and adds the username and password to pConfig.
      Parameters:
      pConfig - The request configuration being created.
      pLine - The header being parsed, including the "basic" part.
