Examples of org.apache.http.protocol.HttpContext

org.apache.http.protocol.HttpContext
A context for executing a request. The context is used to tie together the request, the response, and optional application data. It is also used for internal data. Attribute names starting with the prefix "http." are {@link #RESERVED_PREFIX reserved} for internal data. @author Oleg Kalnichevski @version $Revision: 558111 $ @since 4.0
