I normally use git behind a proxy. Hence I have those set in my global config. git config -l --global has entries for http & https.
However for accessing the corporate git repo, I have to unset the global proxy and then clone.
Is there an alternative where I don't have to change the global settings like this?
Have you tried setting environment variables for http_proxy, https_proxy, and no_proxy?
Take a look at these two answers here on SO:
