I'm dealing with a Java web application that accepts data from one source, formats it, and sends it off to a destination. The app is hardcoded to send to one destination... yes, that sucks, but that's the way it is, and nobody has time to untangle it. The source is going to send data to one IP. Yes, they could send to 2, but they won't, I don't know why, and it would take weeks to go through US government bureacracy to find out why with little hope of changing that. But, we want to make the formatted data available to two different messaging buses. So, we would like one instance of httpd to not only proxy the traffic in to Tomcat, but also "copy" it off to a second VM that runs another instance of the app, which will format the data and send it off to a second messaging bus. I know folks are going to be screaming that this is all wrong, the app sucks, the *real* answer is to do X Y or Z... but we have a deadline, and I was hoping to do this in httpd rather than have one of the developers cobble up the code to do this at the application layer. -- *********************************************************************** * John Oliver http://www.john-oliver.net/ * * * *********************************************************************** --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
