  == HTTP execution context ==
  
-   Maintaining processing state. Persisting state between request executions using local context.
+     Originally HTTP has been designed as a stateless, response-request oriented protocol. However, real world applications often need to be able to persist state information through several logically related request-response exchanges. In order to enable applications to maintain a processing state HttpClient allows HTTP requests to be executed within a particular execution context, referred to as HTTP context. Multiple logically related requests can participate in a logical session if the same context is reused between consecutive requests.        
+ 
+     HTTP context functions similarly to java.util.Map. It is simply a collection of arbitrary named values. Application can populate context attributes prior to a request execution or examine the context after the execution has been completed. 
+ 
+     In the course of HTTP request execution HttpClient adds the following attributes to the execution context:
+ 
+     * '''http.connection''' - HttpConnection instance representing the actual connection to the target server.
+ 
+     * '''http.target_host''' - HttpHost instance representing the connection target.
+ 
+     * '''http.proxy_host''' - HttpHost instance representing the connection proxy, if used.
+ 
+     * '''http.request''' - HttpRequest instance representing the actual HTTP request.
+ 
+     * '''http.response''' - HttpResponse instance representing the actual HTTP response.
+ 
+     * '''http.request_sent''' - Boolean object representing the flag indicating whether the actual request has been fully transmitted to the connection target.
