A domain name is pointing to the web server named "Rewrite" (asp.net mvc application). I would like to query the database and rewrite all the pages from another web server according to subdomain name. Each customer has a specific subdomain. Basically, every page will be generated from another web server. I just want the "Rewrite" web server to show the pages from another server which will be selected dynamically according to the subdomain name.
For example:
If user1.mydomain.com is requested to the mydomain server that will use the web server www1, but the url on the client side won't change: user1.mydomain.com
If user1.mydomain.com/Report is requested to the mydomain server that will use the web server www1 (so www1/Report), but the url on the client side won't change: user1.mydomain.com/Report
If user2.mydomain.com is requested to the mydomain server that will use the web server www2, but the url on the client side won't change: user2.mydomain.com
I've read we can add a rewrite rule in the web.config file, but it seems to be a static solution. Unless I can have an automated process to modify the web.config file automatically when we need to create/modify/remove a new client (subdomain) and create a long configuration list. Also, we can have a few thousand clients.
It is a new architecture solution, so the web servers can be hosted on Azure App Service or it can use IIS on a VM.
Also, will that work with a SSL wildcard?
Any idea would be welcome.
What you are describing is a reverse proxy server. You can do this with IIS but as you mentioned the rules are somewhat static, so for every "user#" to "www#" pair you may have to setup a new rule, unless maybe the number on the www side always matches the number on the user side (I'm guessing that's not the case"

There may be a more efficient way to do this with NGINX (take a look at the LUA and MAP modules as options).
