Dear Martin, thanks for your response. The GASS session does not uses the port 80 (and magno is a local domain). It opens a HTTP session such as
$ globus-gass-server -i -p 8180 http://localhost:8180 and so, you can transfer files using the globus-url-copy (in a grid environment) or simply, using wget to a URI such as http://localhost:8180/out/test.txt, where /out/test.txt is on /, the file is downloaded. It seems rare since using a URI of a web server or tomcat servlet, this application has not problems. So, I guess that httpclient is not ready for this kind of HTTP services, no? By other hand, the application previously set the HostConfiguration, client.setHostConfiguration(config);. I am not the developer of this code, and so I unknown some details. Regards.
