FastCGI PHP runtime configuration

Hello,

I know some of you guys use FastCGI to run PHP scripts. Had anyone figured
out how to load runtime configuration parameters, such as those you can
load from .htaccess if PHP is run as a module, for each instance of FCGI request?
I know it is possible to load different php.ini for a poll of FCGI PHP processes
but I need to be able to load different php.ini or set of runtime parameters for
each FCGI PHP request from the same poll.


Thanks,
Simon
