I posted and idea last week to Ideas and Feature Requests: “Finer  
grained control on caching” ([Finer grained control on caching](http://forum.nginx.org/read.php?10,217748)),  
but since I’m new to this forum/mailing list I have no idea if anybody  
saw this.

I want to find out if this is an acceptable feature request and if  
anybody else sees the benefits of this.

Short summary:  
Add a new directive fastcgi\_cache\_key\_suffix  
Construct the caching filename like this md5(fastcgi\_cache\_key) . ‘\_’ .  
fastcgi\_cache\_key\_suffix
