Quick Question: Does CFTHREAD run the Application file?

@sdsinc_pmascari , the following demo. consists of 3 files.  Place them within the same directory.
To run the demo, just launch testpage1.cfm in the browser.  

Result:

• with cfhttp in the thread, Application.cfc is included twice when testpage1.cfm is launched.
• with cfinlcude in the thread, Application.cfc is included only once when testpage1.cfm is launched.

Application.cfc

<cfcomponent>

    <cfscript>
        this.name = "MyTestApp3";
        this.applicationTimeout = "#createTimespan(1,0,0,0)#";
        this.loginStorage = "session";
        this.sessionManagement = "true";
        this.sessionTimeout = "#createTimeSpan(0,0,20,0)#";
        this.setClientCookies = "true";
        this.setDomainCookies = "false";
        this.scriptProtect = "all";
 	    this.enableNullSupport = false;	  		
    </cfscript>

    
	<cffunction name="onApplicationStart" returntype="boolean">
		<!--- Initialize number of page hits at the beginning of the application --->
		<cfset application.numberOfPageHits=0>
		
	    <cfreturn true>
	 </cffunction>

	<cffunction name="onRequestStart" returntype="boolean">
	 	<cfargument name = "targetPage" type="String" required="true"> 	
		
		<!--- Count the number of page hits --->		
	 	<cflock scope="Application" timeout="5" type="Exclusive">	 		
	 		<cfset application.numberOfPageHits=application.numberOfPageHits+1>
	 	</cflock>
	 

		<cflog text="#arguments.targetPage#" file="PagesHits">
     	<cfreturn true>
	</cffunction>

</cfcomponent>

testpage1.cfm

<cfthread action="run" name="myThread">
        <!--- 
        Test, in turn, with cfhttp then with cfinclude.
        Each time, change this.name in Application.cfc to a new value,
        for example, "MyTestApp1", "MyTestApp2", "MyTestApp3", etc.
        to ensure that a new application starts each time.
        --->

<cfset variables.result="We're in page testpage2.cfm. The time is #now()#.">
<cfoutput><p>#variables.result#</p></cfoutput>

As I said, it all depends on the code. So, can you please share the code you intend to use?

It is difficult to say without seeing the code. Could you share a sketch of the code or pseudocode?

It's a reasonable one, yes. Perhaps another one to try is instead to add a cflog (or writelog in cfscript) to track reaching a given point or not, putting that in both.

And I'd expect the cfthread call would NOT run the application.cfc/cfm, but just the call to the page DOING the cfthread call. But it will be interesting to hear what you find.

Indeed, when you may report results, tell us also what cf version you're running (for others who find this discussion in the future, wondering the same question you asked).

Finally, I'd recommend you add a log line not only in your application.cfc's onrequest method, but also in its pseudo constructor as well, meaning outside of ANY methods/functions, such as the very top.
