I am connecting to internet via my schools proxy server. But it needs to enter an username and password to access. So is it possible to configure a proxy server with username and password authentication in Tileproxy?

Locate the user manual for the open source "Curl" package somewhere on the internet. It details how to set up the http_proxy environment variable.My guess is that it's something likehttp://username:password@proxyname:proxyportor maybe it is another environment variable similar to http_proxy... but in the formatusername:passwordChristian
