Request: Limit number of parallel uploads

I wish the Upload box had a feature to set a maximum number of connections to upload in parrallel.
Think of this:
User selects 100 files of 2mb
Uploading starts with 100 files at 10 percent there is a connection issue. At that point each file has barely started uploading, and none is finished yet, but 20 mb data is used. If the component would upload only 4 at a time, the same scenario would have over 8 files succesfully uploaded, wich means that 16 mb of data is not wasted.

Hi Wouter, 

Greetings from Syncfusion support. 

We have checked with your requirement. There is no direct support to set a maximum number of connections to upload in parallel in our Essential JS 1 Uploader. However, we have the same feature in our EJ2 Uploader as "Sequential upload". 

Essential JS 1 is the first-generation JQuery based JavaScript UI framework from Syncfusion. We will continue to develop, maintain and support this version for several more years. However, please note that new feature development will only occur in Essential JS 1 if an equivalent control is not yet available in Essential JS 2. Starting with the Volume 4 2017 release, we have shipped a beta version of the second generation of the Essential JS library (Essential JS 2). 

By enabling this feature (by setting "sequentialUpload" as true), we can upload multiple files sequentially (one after the other) to the server. If the file uploaded successfully or failed, the next file will upload automatically in this sequential upload. We have showcased this feature in our online demo site and documentation. Please find the details from the below link, 

Please get back to us if you require any further assistance.
