Moving cache to SD Card? Is it possible? Is it possible to move app cache which is stored o Internal Storage on android to sd card? I have limited space on my device, and I want to free up some space (Well, actually the cache is taking most of my internal space) by moving my application cache to the SD Card.

Well, i know that cache can be deleted easily, but it's a pain to delete it every few hours to ensure that there's no "Low Memory" notification hanging..
There's also my Browser &amp; Chrome cache, which could fill my Internal Storage in a matter of minutes.
it is possible, but you will need to get a root. 
FolderMount allows to transfer not the apps but their cache. This program requires root access. If you don’t know what root is then go here and here to read about how to gain root access.

Cache transfer is performed in a few simple steps:

Open FolderMount and press “+” in the top right corner.
Name an app that has leftover cache in the internal memory.
Press “Source” and indicate the folder with the app’s cache. It is located in Android/obb/the folder with the app’s name.
Press “Destination” to choose a folder on the SD card for the transfer.
After every field is filled out, press the check mark in the top right corner and select the “pin” next to the Name field.
