NET sends the response body to the client, it invokes our callback method. Our PushStreamContent callback starts writing a zip file directly to the response body , downloading the files asynchronously one at a time and adding them to the zipped content.

When our callback returns, ASP. NET completes the response. At no time are any threads blocked waiting to read the source files from their URLs, nor are any threads blocked waiting to write to the output response stream. The zip file is not held in memory. It is streamed directly to the client, compressing on-the-fly. In fact, for large files, not even a single file is read entirely into memory. Each file is individually compressed on-the-fly.
