I have a downloadable product store.
My problem is that some of my files range over 1GB which is quite often, too large to download in one sitting. I want my customers to be able to pause their download session during the product download and restart at a later time.
Such as here
I've found two extensions that claim to do this, one at £150 that simply does not work for us. And one at £1,500 that is simply too much to pay.
I understand this is a common feature with modern browsers however we want to embed this directly into the 'Downloadable Products' tab in a magento account page. Not to mention most browsers have trouble interrupting downloads.
My question is, are there any other extensions which are capable of this? If not how would one start with building this functionality in, programmatically?
