Application Server - Server.ClearA5iCache() Method
An obsolete method that was removed in version 11.
This method clears the server's Application cache, causing it to re-read and execute the a5_application.a5i file upon the next request. When making changes to the Application settings, such as connection strings, the cache must be cleared, either by using this method or by restarting the server.
For example, say you have published your application and you are testing it. You then edit the Publishing Profile and change a connection string and publish any file (causing an updated a5_application.a5i file with the new connection string definition in it to be published), and you then continue testing your application. You will find that the new connection string is NOT being used because the Application Server has cached the connection strings.
To force the Application Server to use the new connection strings you can call an .a5w page that executes the new Server.ClearA5iCache() method, as opposed to stopping and restarting the server.
Clearing the A5i cache also clears the AEX cache. As such, you will not be able to use a function from your AEX until the next request. This is most easily accomplished with a Response.Redirect() call immediately after Server.ClearA5iCache().
Change in behavior: As of build 3639, when you clear the A5i cache, the AEX cache is not cleared until the current page completes executing.
