Windows IIS 10 - ISAPI Filter Development

Hello,

I would like to development an ISAPI Filter that performs the following functionality:

1. Load user virtual directory list from:

C:\\Windows\\System32\\inetsrv\\config\\applicationHost.config

2. Load physical user directory list from:

c:\\www2\\

will be 13,000 directories. Example:

user1
mikesite
usersite
user2

3. Store step1 and step2 information in memory and update memory every 1 minute.

4. When a HTTP request (look at header information for subdomain like usersite.mydomain.com is found. Perform check from step 3 and if application does not exit then convert directory to application before before HTTP request is completed so user can access site without getting an error.

For example, if a user accesses usersite.mydomain.com and an application does not exist a configuration error occurs, because the user directory is listed c:\\www2\\web.config

We are doing this to prevent this configuration error.

Purpose: The purpose of this project is to prevent IIS from crashing. When the applicationHost.config file reaches 3.2 MB IIS crashes. As a result I would like to create applications only for active users and not waste resources. As a result only active users will have their directory converted to an application.

This is an idea if you have a better way for implementation we can do it that way.

Thank you.
