Note: In order to do this you must still have root access.

The first step would be to Root your phone.

Now:
cd /data/data/com.android.browser/cache
rm -R webviewCache
mkdir /sdcard/webviewCache
ln -s /sdcard/webviewCache webviewCache

Q:What am i doing this for?

A: You are changing to the cache directory.
Deleting the web cache directory.
Making a new one on the sdcard.
Linking symbolically the new one to the old one.

Once this proccess is done it will create a folder named WebCache on your SD card.

After this has been done you can surf the web and save some of your phone memory since there is still no way to save apps on your SD. This will leav more space for apps on your phones memory.

To your phone it is as though the webviewCache is still in the same spot. In reality it's on your SD Card where you have tons of room for it.
