Re: HttpRecoverableException when using httpClient only in certain si tuation

[Michael Becke <be...@u.washington.edu>]

Hi Jing,

Are you using one instance of HttpClient from multiple threads?  If so, 
makes sure you have a look at 
<http://jakarta.apache.org/commons/httpclient/threading.html>.  If the 
problems continue please post some sample code and a wire log 
<http://jakarta.apache.org/commons/httpclient/logging.html>.
