In the posts of [Feedtools question - Rails - Ruby-Forum](http://www.ruby-forum.com/topic/63984) i have got the  
thread question,and the enviroment is webrick. And according to Ray’s  
suggestion,I change the value of allow\_concurrency in the base.rb to  
true,and then webrick can work,although it will brings lots of other  
error,it can at least to debug what i want.  
Now, I change my enviroment to Apache+scgi to a multithreaded  
context,however,no matter how I change the value of allow\_concurrency,it  
will not work at all.  
Then,what should I do in this kind of situation:  
controller A will send a request to controller B and will not return  
until controller A got the response from controller B

Thanks
