Hi, Yesterday I did a first implementation of HTTPS proxying using HTTP CONNECT tunneling for Zn+Zdc, this should now be tested by a wider audience. With this new feature it should now be possible to access HTTPS Urls from behind an HTTP proxy. This is for all OS platforms. Thanks Nicolai for finding the spec reference and Torsten for the push.

Let's hope it works for others too. I did not yet test proxy authorization but I think it should work like before. An HTTP Proxy can be set in World > System > Settings Here is some code to do a simple test ZnClient new get: 'https://s3-eu-west-1.amazonaws.com/public-stfx-eu/test-2050.txt'. ZnClient new get: 'https://s3-eu-west-1.amazonaws.com/public-stfx-eu/small.html'. ZnClient new get: 'http://stfx.eu/small.html'. ZnNetworkingUtils default isProxySet. ZnNetworkingUtils shouldProxyUrl: 'https://s3-eu-west-1.amazonaws.com/public-stfx-eu/small.html' asUrl. Regards, Sven
