First of all, I highly appreciate the developer for this great plugins. Additionally, as I came to know there is a new major release coming up shortly I would like to mention the most required missing features of the current version. The feature is simple - it shouldn't return the Cache from the disk for the following scenario:
1. When accessing the mobile version
2. When accessing the HTTPS version
3. When there is additional url query (for ex - /sample?id=01)
4. 404 Not found
For all above said case it should return the live version. Additional hooks if possible are welcome for controlling by other modules.
