This sounds like a perfect example of mod_perl lacking "PR". MP had an
almost full set of features from Apache from day 1. And it was easy to
add one when you need it (Doug did this for me, for example). Had you
known about mod_perl first, would you have gone to the PHP camp?

PHP has been patched again and again "stealing" MP features. I don't
have a deep knowledge of PHP, but I have serious doubt about it, from
my experience running one server using it. I don't intend to start a
flame war here, but just want to share my own experience. And the point
is that there is need for some more PR for mod_perl.

When you go to httpd.apache.org, you can hardly find mod_perl
mentioned.  Even mod_python is there. :-( This is not good for
mod_perl.

Any idea about the share of mod_perl in the server market recently?

Jie
