Open a socket or other solution?

[David Herrero]

I have the following problem: I'm trying to modify an existing apache 
module to change the value of ap_deamons_limit at
run-time. I need this module receives a query through a socket or 
something similar and then it modifies that parameter. The problem is
that if I do this, the web server hungs, waiting for a socket 
connection and if alternatively I use a child process to
host this socket connection I can not access that parameter. How can I 
solve this?

Thanks
