I am new to the Yii framework and i Changed a Folder name inside of my project and it took about 15 minutes for Yii or web server to understand it and not showing error about the file path .
I checked out my Apache Web server configuration (it is local) , it does not contain any caching on it and i did not install any caching software on it so i was just thinking maybe there is some kind of caching mechanism turned on in this framework by default, is it ?
Yii has various caching components built in.
The link below gives an overview....
