Look at the problem from the opposite direction. There is not that much overhead in including http in the perl processes actually doing the work, and (unsurprisingly...) http turns out to be a reasonable protocol to forward http requests instead of inventing something else. So, consider mod_perl to be the backend perl process with a non-mod_perl frontend using ProxyPass and/or RewriteRules to talk to it amd you end up with the same thing, except more flexible, with a single config file style, and the ability to test the backend with only a browser.

The issue in question was getting the perl core out of the address space of the httpd process entirely :) Velocigen does this nicely (though there is a performance penalty) and even allows degicated machines runnign the perl services that talk to the webserver over sockets.

mod_perl shared perl instances?
Hiya :) OK... mod_perl embeds an instance of Perl inside the Apache system, and with Apache::ASP allows us to mix perl/html. Good :) The problem is that these processes are 'heavy'. Is there any way to simulate the actions of "Velocigen" in that we could have a few (configurable number) of perl's running that round robin to work with Apache::ASP to render pages? This should also seperate out the systems a bit for stability.
