Efficient HTTP file download by chunks in Unreal Engine C++
Chunk downloading is a technique used to retrieve large binary data from the server in separate parts, ensuring reliability and compatibility across different platforms. Unreal Engine’s HTTP module has a limitation of 2GB for binary HTTP response content due to internal restrictions (specifically, TArray<uint8> uses the int32 size type, which has a maximum value of 2,147,483,647, approximately 2 GB in our case). To overcome this limitation, we can use the Range HTTP header supported by most servers, without requiring any file preparation or segmentation....
