  • The BIND DNS server has already been deprecated and removed from Plesk for Windows.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS. We strongly recommend transitioning to Microsoft DNS within the next 6 weeks, before the Plesk 18.0.70 release.
  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.

Question HTTP/2 Server Push for Apache possible?

daanse

Regular Pleskian
Hi,
with latest Plesk (17.5.x and Debian 8.9) can i enable HTTP/2?
I have nginx completely disabled (some years ago) and i don't want to enable it.

Is it possible with Apache2 only? If yes, how? I didn't find helpful KBs
 
Hm, i have a Server with multiple Joomlas and Wordpresses.
Can i just install NGINX and regenerate all vhosts configs?
Will that work on the fly? or do i have to take care over ALL htaccess files and so on?
 
In general, everything should work properly, but you understand that nothing is perfect and problems are possible.
If you have something special in your .htaccess files I can recommend you try to use this Plesk extension - htaccess to nginx - Plesk Extensions

I don't know of anyone running Apache with http/2 support on Plesk. It can be done, but it's very convoluted and you might run into various packaging issues - dependencies, yum priorities and all that. For CentOS 7 I've got a non-Plesk test server running Apache 2.4.27 with http/2 support, but there are caveats:
- You need CentOS 7.4 with the latest OpenSSL 1.0.2k and you must rebuild httpd with http/2 support.
- http/2 requires a threaded multi processing module, so prefork won't work. However, if running worker you'll run into problems with various PHP libraries (php-imap comes to mind) which aren't thread safe and will experience random crashes.
- No NPN support, just ALPN, so certain older browsers will still use 1.1
For Plesk I'd stick with sw-nginx as proxy for Apache for the time being.
