Method Detail

readHeaders

public static Map<String,String> readHeaders(InputStream in,
                                             boolean req)
                                      throws IOException

Read header properties from the specified input stream. Only a restricted syntax is allowed as the syntax is in our control. Not allowed are: - multiline or line-wrapped headers are not not - charset other than utf-8. (although i would have preferred iso-8859-1 ;-)

Parameters:

in - the input stream

req - true if the input stream includes the request line

Returns:

a map of name value pairs.

Throws:

IOException

readHeaders

public static Map<String,String> readHeaders(InputStream in)
                                      throws IOException

Throws:

IOException

readLine

public static String readLine(InputStream in)
                       throws IOException

Read a line terminated by '\n' optionally preceded by '\r' from the specified input stream.

Parameters:

in - the input stream

Returns:

Throws:

IOException

readBody

public static byte[] readBody(InputStream in)
                       throws IOException

Throws:

IOException
