DESCRIPTION
Sometimes, it is very important to know where request came from. Unfortunately, it isn't obvious. ARS SDK describes several methods to get information about request source, but none of these methods give full information. The following script in SCRIPT ONE section demonstrates how to get full information about request source.
Note: The GetRequestSource() function returns a valid value in script policy "pre"-handlers only such as onPreCreate, onPreModify, etc... To know a request source in "post"-handlers, you should first save the source in "pre"-handler in some Request's control as it shown in SCRIPT TWO section.

' This function determines request source
' Possible return values:
' "AD DirSync" - request came from Active Directory by DirSync
' "DB Replication" – request came from SQL database by replication
' "ARS Internal" – request made by ARS Administrative Service
' "Quick Connect" – request made by ARS Quick Connect, only Quick Connect 3.x is supported
' "MMC Interface" - request made by ARS MMC Console
' "Web Interface" - request made by ARS Web Interface
' "ADSI Provider" - request made by external script or application that works with ARS through ARS ADSI provider
' something else - undetermined request source
