No, I'll call you...
Ok, so I am working on some very long reports and am peddling ideas... Here's the idea: The user runs a very long report, and the request will simply be placed in some sort of queue to be ran asynchronously. The user is told he/she will be notified when it is completed. Then the user surfs away to another portion of the site. Half an hour later when the report finishes, a message pops up on the users screen saying Your report is finished, you may view the result now. My first thought was I could place a receiver JavaScript function in every page in the site, then make an Ajax call to run the report. When the Ajax call returned, it would fire the function and display/alert the message. Well, no dice on that. I tried it in IE and FF. IE actually leaves the TCP connections open until the call returns, but there is nothing listening to receive it. FF actually threw an unhappy error when I tried to navigate away while the call was going, and then it closed the TCP connection. I'm really afraid the correct answer to this is The web is stateless. What you need is a client server app. Convert your entire site to Flex 2 Enterprise and use their sweet messaging services and all your woes will disappear Now, as much as I would like to do that, that's not really an option right now.

RE: No, I'll call you...
I am considering something very similar. My only thought is running a tasks to process the report requests and then send en email to the user with a link to the results. But my problem is some users do not want to wait. So I am considering showing a subset of records and say you can either restructure the request to limit the amount of data or submit it as a request and we will send you the email blah blah Would love to hear other feedback on this topic. -Original Message- From: Brad Wood [mailto:[EMAIL PROTECTED] Sent: Thursday, December 21, 2006 11:50 AM To: CF-Talk Subject: No, I'll call you...

Re: No, I'll call you...
This probably isn't what you want either, but... You could have your report program write to a table when it's complete. The record would consist of who needs to be notified, and the status of their notification. Maybe the session ID or some session variable could be stored. Then you could have a javascript function that you include at the top of every page (like from the Application.cfm) that fires off an ajax call to check this table for the presence of finished jobs that belong to the current session or user or whatever. Does that sound feasible? Cheers, Chris Brad Wood wrote: Ok, so I am working on some very long reports and am peddling ideas...

Re: No, I'll call you...
We have a similar architecture at my work where those long reports are sent as an Async request (Async Gateway) and then user is notified via email when reports are complete.

Re: No, I'll call you...
Brad, We've got an application where the user requests the report, and the actual report generation is handled by an asynchronous event gateway. When the gateway is done generating the report, it then generates an email to the user notifying them that their report is ready. Our users will have a Report Inbox page on the web that will be flex powered, and if they keep that screen up, the report just automatically appears there, but they're free to do other stuff while they're waiting.
