text

public String text(String encoding)

dispose

public void dispose()

This method is already called from text() and bytes(), you do not have to call it if you use those methods.

However, if you use getInputStream(), call this method in those cases when you think you did not read entire content from the stream.

This method clears all remaining data in connections after reading a response. This will help keep-alive work smoothly.

connect

protected T connect()

doConnect

protected abstract T doConnect()

Makes a connection to the remote resource.

Returns:

self.

basic

public T basic(String user,
               String password)

Sets a user and password for basic authentication.

Parameters:

user - user.

password - password.

Returns:

self.

public T basic(String user)
