AW: AW: [geclipse-dev] any experiences with accessing S3 from behindapro

["Stuempert, Mathias IWR" <mathias.stuempert@xxxxxxxxxx>]

Hi Markus,

I don't think these problems are related to each other. Since Ashish's connections are normally working it is not a general problem with auth-http connections. The S3 problem is rather a problem of the apache http client library. This one is configured by either a properties file or by using the jets3t properties wrapper. For reference see http://jets3t.s3.amazonaws.com/toolkit/configuration.html. There are settings like httpclient.proxy-host and httpclient.proxy-port but nothing about authentication. Nevertheless I think these are http client properties and they may not be explained in all details at the S3 configuration pages. Maybe having a closer look at http://hc.apache.org/httpclient-3.x/authentication.html may help.

Cheers, Mathias

There are 'some' known issues here... and it is a platform problem.
E.g. see here: https://bugs.eclipse.org/bugs/show_bug.cgi?id=196780
