Feature request: Add custom error pages and fastcgi intercept errors

[iio7]

httpd is almost useless for anything other than static HTML files. Even though you can use it with fastcgi, there is no way to intercept errors and display a custom error page to a user whenever a 500 error occurs.

Custom error pages (not only 404) is needed.

Also a way for fastcgi to intercept the error so that it can be handled gracefully on production servers.

NGINX does this with fastcgi_intercept_errors on;

Last but not least, the error logging without using syslog doesn't provide any timetamps or IP addresses, or at least a way to disable enabled these. Using syslog clutters the log file.

Anyway, these things are very much needed for a production system running more than just static files.

Someone has already made some patches for httpd please see https://github.com/mpfr/httpd-plus

Other than that, httpd is a great product, the setup and logical configuration is amazing! Well done!
