Multisite does not work when Full Page Cache is enabled (FPC ignores MAGE_RUN_CODE)

[dmitrii-fediuk]

I have 2 VirtualHosts:

Listen 1800
<VirtualHost 127.0.0.1:1800>
    ServerName localhost.com
    DocumentRoot "C:/work/m2"
    SetEnv MAGE_MODE "developer"
    SetEnv MAGE_RUN_TYPE "website"
    SetEnv MAGE_RUN_CODE "discourse_pro"
    RemoteIPHeader X-Forwarded-For
</VirtualHost>

Listen 1900
<VirtualHost 127.0.0.1:1900>
    ServerName localhost.com
    DocumentRoot "C:/work/m2"
    SetEnv MAGE_MODE "developer"
    SetEnv MAGE_RUN_TYPE "website"
    SetEnv MAGE_RUN_CODE "mage2_pro"
    RemoteIPHeader X-Forwarded-For
</VirtualHost>

It is works when FPC is disabled, but does not work if FPC is enabled.
When FPC is enabled, Magento 2 caches the website on the first request, and then shows it for the both website requests, totally ignoring what the site is actually requested.

How many people are using this functionality?

@dfediuk can you describe your use case in more detail? I'm guessing that you've got a multi-site and you're using an apache or load balancer route to 1:N web nodes with a site on a different port. I'd like to understand why you're not using hostnames or url re-write on directory paths for this ( which should be working ).

Did you do this in Magento 1 prior - if so was that just CE?

Thanks!
