It is effectivelly possible to use wildcard subdomain.
We already did that several time and sometime for a very large number of website > 10,000 websites.
There are several possible setting to also take in account the performance.
Over than 1000 websites, it is recommended to:
- Setup the JMS template rule with "ignore master index" = yes
- create a specific "multisites_userexit.php" that compute the master index dynamically.
- Setup the JMS Settings with "enable the letter tree"
If you want to have specific deployed directory for each subdomain,
- You need to create a specific vhost in Plesk - See the plesk help.
If all your slave site point to the same directory in your plesk configuration,
- Setup the JMS template rule with folder tab => action = ignore for all
If you want that we help you setup your environment, this is possible with our billable support that you can order at
