You wouldn't put it in onApplicationStart, but onRequest (cf9+).
onRequest is only triggered on cfm requests, whereas a cfc would trigger
onCFCRequest. (I am assuming your Ajax requests are going to a CFC)
Set up your js vars in onApplicationStart
<cfscript>
application.siteDetail = {"js_sitename"=application.sitename,
"js_website"=application.website,
"js_site_manager_dsn"=application.site_manager_dsn,
"js_client_dsn"=application.client_dsn }
</cfscript>
Then, in your onRequest (though some header include custom tag, included
at the page level, would be better and give greater flexibility)
<cfoutput><script type="text/javascript">var siteDetail =
#SerializeJSON(application.siteDetail)#;</script></cfoutput>
Then, in your JS, access the vars from the JS obj
... // some JQuery Ajax call data object
data: $.extend(true,{},siteDetail,{someArg:1,someArg2:'myArg'})
There's probably many ways to handle all of this, but putting the output
in your onApplication or onSession methods is not the way to go.
