Subject [jira] Commented: (HTTPCLIENT-647) https connection over proxy with auth fails
Date Wed, 18 Apr 2007 08:05:15 GMT

    [ https://issues.apache.org/jira/browse/HTTPCLIENT-647?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12489643
] 

Satoshi Nakamura commented on HTTPCLIENT-647:
---------------------------------------------

After a server disconnects a connection after sending 407 response, isOpen() continues to
return true because it doesn't care the server disconnects. When closeIfStale() is called,
it detects that the server disconnected the connection and resets isOpen flag to false. At
this time isOpen() returns false so that it tries to reopen a connection again. Without this,
it tries to write to the closed connection and throws IOException.

I'll post logs later.

> When I try to connect to a https server using a proxy which requires authentication,
httpclient fails. It is because the proxy server close the connection after sending 407 response
and httpclient doesn't reopen a connection. The proxy server which I confirm that this issue
occurs is delegate 9.5.6.
> Here is a patch to fix this issue.
