Subject [jira] [Updated] (HTTPCLIENT-1168) HTTPClient doesn't send authentication header in threaded environment
Date Mon, 27 Feb 2012 21:05:48 GMT

     [ https://issues.apache.org/jira/browse/HTTPCLIENT-1168?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Oleg Kalnichevski updated HTTPCLIENT-1168:

         Priority: Minor  (was: Major)
    Fix Version/s: 4.2 Beta2


The race condition is caused by HttpContext instance being shared for all threads of execution.
While theoretically HttpContext can be shared by multiple execution threads, authentication
state clearly cannot. 

I'll see if I can fix this issue by synchronizing access to AuthState instances or by updating
the documentation.

> Using HTTPClient with multiple threads and basic authentication seems to create a race
condition. The request headers sometimes don't contain the authorization entry, which results
in a 401 (although the username and password credentials are correctly set).
