Subject Re: HttpClient 3.0-rc2: problem reading ssl encrypted data via proxy
Date Mon, 02 May 2005 19:42:29 GMT
Gebhard,

Simply put HttpClient fails to find the required proxy credentials:

> [INFO] HttpMethodDirector - No credentials available for BASIC
'XGATE'@10.5.8.66:3128

Just wondering if there is any particular reason you are using this
deprecated method?

> httpclient.getState().setProxyCredentials("XGATE", " 10.5.8.66", 
  new UsernamePasswordCredentials("uid", "pwd"));

Besides, please note a superfluous blank in the host name: 

" 10.5.8.66" whereas it should probably be "10.5.8.66".

Hope this helps

Oleg
