Do you know a webinterface for the configuration of webservers (like Apache httpd or nginx) which writes/reads the config (Webservername, Certificates, Alias, IP-Protection, Redirects, etc...) into/from a database instead of the config files?
So to create the webservers config files a different step is needed: Read the config from the database and write the config files.
If you know such a software (commercial or free) tell me the URL where they document the database format and if it matches the above mentioned requirements and you are the first one, who mentioned this product/solution, you will receive $10!
e.g. cPanel is a wrong answer! It writes the webserver configuration directly into config files and NOT into a database!
A correct answer would have been Aetolos ([url removed, login to view]), but that was mentioned by me and not you! :-)
(Maybe you have written something like this by yourself. Then talk to me! Maybe I am interested in taking a closer look / buy it (for much more than $10).)
