sendRequest

public static HTTPResponse sendRequest(HTTPRequest request,
                                       java.io.InputStream in,
                                       java.io.BufferedWriter out,
                                       java.io.OutputStream dataOut,
                                       HTTPLoader loader)
                                throws java.io.IOException

Throws:

java.io.IOException

readHeader

public static void readHeader(java.io.InputStream in,
                              HTTPResponse rval,
                              HTTPLoader loader)
                       throws java.io.IOException

* This method reads from a InputStream the response header after a request was sent to the associated BufferedWriter. Lines are read until a double newline is encountered which signifies the end of the header. Header fields and values are stored in a Hashtable which is returned. The HTTP result is stored as the key 'HTTP'. This will always be a 3 digit value stored as a String.

Throws:

java.io.IOException

read

public static java.lang.String read(java.io.InputStream reader,
                                    java.io.OutputStream dataOut,
                                    HTTPLoader loader)
                             throws java.io.IOException

* This method reads from the InputStream until there is nothing left to read. Do not use this method if the last line does not end with a newline or if the connection is going to hang, otherwise, this method will block.

Parameters:

reader - This is the InputStream to read from.

Returns:

Returns as a String the data read from the reader.

Throws:

java.io.IOException

read

                                    HTTPLoader loader)
                             throws java.io.IOException

Returns:

Returns as a String the data read from the reader.

Throws:
