How to detect if a script is running via a scheduled task

Question

Is there a way to detect if a script is runned by a scheduled task.

I have a script which gives throws a ClientAbortException because I am using cfflush. I need to detect if the script is running via a scheduled task so the script can run successfully.

this is a duplicate qustion http://stackoverflow.com/questions/13977831/how-do-i-determine-if-a-scheduled-task-was-ran-automatically-or-ran-in-a-browser/13978558#13978558 — genericHCU, Feb 07 '13 at 11:25
Here's something to look at regarding the error - http://stackoverflow.com/questions/12141659/connection-reset-by-peer-socket-write-error-cfcontent-on-coldfusion-10. Seems odd, as it seems to imply that the task scheduler is terminating the connection to the server after the request is made but before it is complete. — Barry, Feb 08 '13 at 18:40
And you might also consider using cgi.remote_addr to determine if it is a scheduled task. It contains the IP address of the remote host making the request. For a scheduled task, it will be the IP address of your server. — Barry, Feb 08 '13 at 18:43
@barry The drawback here is when you have multiple instances of your app deployed over multiple server, you need to configure the IP-address somewhere to check if the CGI.REMOTE_ADDR is equal. BTW, i found a bugreport regarding the error: https://issues.jboss.org/browse/RAILO-727 — Willem de Wit, Feb 11 '13 at 08:10

It seems that you can check it via CGI.HTTP_USER_AGENT:

<cfif CGI.HTTP_USER_AGENT NEQ "CFSCHEDULE">
  <cfflush>
</cfif>

This is a duplicate question as Travis said, but another answer is you could add a url parameter to the scheduled task something like ?auto= which would allow you to check the url scope to determine how it was ran.

that would also allow you to bypass the cfflush in the browser if you wanted to. – genericHCU Feb 07 '13 at 13:34
