Defines the basic formatting and structure of Authorization header classes. | |
Formats and encodes its contents as Authorization: basic header_value. | |
Provides low-level access to the HTTP client-side protocol. | |
Managers threads and host connections used in servicing RWHttpAgent requests. | |
A derived RWHttpHeaderBase that formats its contents as Content-Length: header_value. | |
A derived RWHttpHeaderBase that formats its contents as Content-Type: header_value. | |

A derived RWHttpDateHeader. Defines the HTTP If-Modified-Since header request. | |
Defines an HTTP range for requesting a portion of a document. | |
Formats its contents as Range: bytes=start_range - stop_range. | |
The class for all HTTP protocol reply messages. RWHttpReply is a subclass of RWNumReply, and provides additional methods for retrieving returned HTTP header information. | |
Defines the HTTP request methods in the HTTP specifications. | |
An abstract base class from which the methods for handling message bodies are derived. | |
Defines how to read a streamed message body. | |
Defines how to read a standard message body. | |
Provides implementation specific details for HTTP clients over normal network sockets. | |
A derived RWHttpGenericHeader. Defines the HTTP User-Agent header request. | |
