Hi,
We've got a WordPress site that requires a proxy to access external resources, like Google Calendar .ics files. Your plugin does not seem to support WordPress' global proxy configuration, nor does it have an option to configure a proxy for the plugin. Is there a way to add proxy support to the calendar plugin?
We've tested with a test WordPress (same .ics), hosted elsewhere, and it works well and looks great. It's a shame that it won't work in our production environment.
