No way to explicitly set proxy server used to connect

[antgel]

As per emails. Perhaps add the tip to the documentation about the environment variable that makes LWP::UserAgent use the existing ("standard") envvars.

Thanks. :)

Agreed - a workaround is to set proxy in your environment variables, and set PERL_LWP_ENV_PROXY to true:
export http_proxy=http://your.proxy:8080
export PERL_LWP_ENV_PROXY=1

Better (and on the ToDo list) would be to implement a proxy attribute which is passed through to the LWP::UserAgent in the Oauth2 client.
