I'd like to know how to change the external app config per virtualhost via the Apache config. Specifically, I want to change the Memory Soft Limit and Memory Hard Limit for a specific virtualhost's php lsapi to a very high number, and keep it the default for all the others. I realize I could probably add another special external app and change the php handler for that site. but i want to avoid this solution, for fear that any user clever could work out how to do it (its a shared hosting environment) I also attempted to use RLimitMEM to no avail I've also tried searching for a list of all the compatible directives that can be used in apache config, but couldnt find anything. any hints? Also, as im using php suExec id also like the ability to change the PHP suEXEC Max Conn option per vhost also. for example, all sites have max 5, except one that is allowed 10.
