Hi guys  
Currently, I have the following setup:

> defaults  
> log global  
> mode http  
> retries 3  
> balance roundrobin  
> option abortonclose  
> option redispatch  
> contimeout 10000  
> clitimeout 150000  
> srvtimeout 300000  
> maxconn 500000

But I want to limit the number of simultaneous accesses per subdomain.  
For example, say the limit is 500 active connections per subdomain:

[a.mysite.com](http://a.mysite.com) → 500 active connections  
[b.mysite.com](http://b.mysite.com) → 500 active connections  
[c.mysite.com](http://c.mysite.com) → 499 active connections

If someone tries to access either “a” or “b”, they won’t be allowed.  
But it’s OK if someone tries to access “c”.

Thanks in advance.
