Large File Upload Solution

The traditional HTML method has been difficult to meet the large file upload. Don't say it is 100MB,50MB to the server is very large, service not only to open a link waiting for this file upload complete, but also to allocate the same size of memory to save the file on the server to the pressure is quite large.

In a real-world network environment, files around 10MB need to be implemented using controls. On the one hand because the domestic network environment is not very stable, on the other hand, from the server load considerations.

Like QQ mailbox in the super-large attachment upload function, 115 network disk in the large attachment upload control, Huawei Network Disk (Dbank), Jinshan fast disk they are all using the control to achieve large file upload function.

They use a control to divide a large file, such as 1G, into small chunks, each of which is about 128KB, and then loop through the upload until it is finished uploading.

Each server receives a small chunk, which is equivalent to receiving a separate file, which is written directly to the hard disk. Finally, put together all the documents that were accepted.

The advantage of this is to reduce the pressure on the service side, improve the load capacity of the service side, so that the server can handle more user requests.
