Transport exceptions
Transport exceptions are those caused by input/output failures such as an unreliable connection or an inability to complete the execution of an HTTP method within the given time constraint (socket timeout). Generally transport exceptions are non-fatal and may be recovered from by retrying the failed method. However, special care must be taken when recovering from exceptions in non-idempotent methods (refer to HTTP transport safety for details).

In some circumstances, usually when under heavy load, the web server may be able to receive requests but unable to process them. A lack of sufficient resources like worker threads is a good example. This may cause the server to drop the connection to the client without giving any response. HttpClient throws NoHttpResponseException when it encounters such a condition. In most cases it is safe to retry a method that failed with NoHttpResponseException. Adobe illustrator cs6 free download for mac full version.
