Problems using Go App Engine behind a proxy

I'm trying to run the example application hosted at: https://github.com/googlesamples/cloud-polymer-go, but when running it behind a proxy, I get the following errors:

$ goapp serve dispatch.yaml frontend/app.yaml backend/app.yaml

The variables:

$ echo $http_proxy 
http://asusis-isa2.personal.com.py:8080/
$ echo $https_proxy 
http://asusis-isa2.personal.com.py:8080/

Are correctly set.

I works with a direct Internet connection.

I'm under Ubuntu 14.04.

EDIT Looks like there is a defect in the SDK around using a proxy with URLFetch.

https://code.google.com/p/googleappengine/issues/detail?id=544

Try setting the uppercase versions of those environment variables, HTTP_PROXY and HTTPS_PROXY. The gcloud launcher requires them that way so I assume goapp does as well.

Using an HTTP proxy

If you are running gcloud preview app behind an HTTP proxy, you must tell gcloud preview app the name of the proxy. To set an HTTP proxy for gcloud preview app, set the http_proxy and https_proxy environment variables. Note that you must specify the full path for the app.yaml file.

Using Windows (in Command Prompt):

$ set HTTP_PROXY=http://cache.mycompany.com:3128
$ set HTTPS_PROXY=http://cache.mycompany.com:3128
$ gcloud preview app deploy DIRECTORY/app.yaml

Using the command line in Mac OS X (in Terminal) or Linux:

$ export HTTP_PROXY="http://cache.mycompany.com:3128"
$ export HTTPS_PROXY="http://cache.mycompany.com:3128"
$ gcloud preview app deploy DIRECTORY/app.yaml
