[Pharo-project] Issue 3774 in pharo: Cannot fetch content from https:// url

Status: Accepted Owner: laurent....(a)gmail.com Labels: Importance-High New issue 3774 by laurent....(a)gmail.com: Cannot fetch content from https:// url http://code.google.com/p/pharo/issues/detail?id=3774 Url absoluteFromText: 'https://www.google.com') retrieveContents or HTTPSocket httpGet:'https://www.google.com'. fail because they don't like https://. How can I get content on https:// ? Sven: You can't. This is a problem. There is http://www.squeaksource.com/SqueakSSL.html but it is not so Pharo friendly as well as incomplete (depending on your platform, worst for Mac OS X, less for Linux, best for Windows).
