- refactor code used multiple times spread over sg/fg into
one single location.
- allow aborting requests.
- Provide two common request types:
* FileRequest: Save response into file
* MemoryRequest: Keep resonse in memory (std::string)
- extend HTTP::Client interface:
* urlretrieve: Save url to file (shortcut for making a
FileRequest)
* urlload: Get respons into memory (shortcut for making
a MemoryRequest)

|
* NAME
|
|
* netChat - network chat class
|
|
*
|
|
* DESCRIPTION
|
|
* This class adds support for 'chat' style protocols -
|
|
* where one side sends a 'command', and the other sends
|
|
* a response (examples would be the common internet
|
|
* protocols - smtp, nntp, ftp, etc..).
|
|
*
|
|
* The handle_buffer_read() method looks at the input
|
|
* stream for the current 'terminator' (usually '\r\n'
|
|
* for single-line responses, '\r\n.\r\n' for multi-line
|
|
* output), calling found_terminator() on its receipt.
|
|
*
|
|
* EXAMPLE
|
|
* Say you build an nntp client using this class.
|
|
* At the start of the connection, you'll have
|
|
* terminator set to '\r\n', in order to process
|
|
* the single-line greeting. Just before issuing a
|
|
* 'LIST' command you'll set it to '\r\n.\r\n'.
|
|
* The output of the LIST command will be accumulated
|
|
* (using your own 'collect_incoming_data' method)
|
|
* up to the terminator, and then control will be
|
|
* returned to you - by calling your found_terminator()
|
