I know it's not exactly the most efficient, but will it work if we continue with the current MPM model. The difference is that both the server and the client use SOAP as the means of communication. When an event occurs, Apache will delivers the event message via the client's SOAP interface. This way there is no need to keep the connection for too long.
I am looking at an open-source messaging queue implemented in .NET (wsmq.com). I wonder if this is equally and easily implemented in mp2. ----- Original Message ----- From: "Ken Simpson" <[EMAIL PROTECTED]> To: "Perrin Harkins" <[EMAIL PROTECTED]> Cc: <modperl@perl.apache.org> Sent: Thursday, December 22, 2005 2:44 AM Subject: Re: go crazy with me > > Okay, so you basically run two daemons -- mod_perl, and a separate > > multiplexing one -- to handle this?
