(https) SNI Support

[sopi20]

I think it would be pretty cool if roundcube would support SNI when running on a virtual host where more than one https-enabled site is running on the same ip address. I think SNI will be more and more used nowadays, so I really think this feature will give roundcube a good advantage against other ajax-based webmails.

Isn't this a task for the layer below the application (webserver)?

[sopi20]

No. The destination webserver has to support it, but also the client has to. That is, for example, why SNI works like a charm in firefox and opera, but it doesn't on ie (except for the vista version). The only layer below that can support it instead of the application itself is PHP and it's functions (XMLHttpRequest, fsockopen, ...)

servers are going slow in implementing SNI ​https://issues.apache.org/bugzilla/show_bug.cgi?id=34607

how do you propose that roundcube uses the SNI domain to map to a IMAP account?

Apache SNI has been release 2.2.12 (July 2009). Looking for the code for it the SNI hostname is enforced to be the same as the host: HTTP header in apache.

As such this issue is the same as issue #1485194, issue #1485438 and perhaps issue #1484897 which all seem to be deriving the hostname to be the domainname in various ways.

probably should mark this a duplicate of #1484897 after looking at all of them closer
