Temporary physical space required?

Hello,

Is is possible to build the zip file in memory (using stream or what not), then to send it to the browser instead of first creating a temp zip file on local disk then to send it to the browser?

OR

Is there any way to know when the client browser has completed download so that we can delete the temporary zip file from server?

My problem is that I am short in disk space and I don't want to keep unnecessary files on the server.

Thank you.

1) It is impossible

2) Yes, it is possible. Just check "Spanning a zip file to user browser" demo code from the component documentation

Is it possible to pack (with zero-level compression) few files on-fly and stream it directly to the clients browser?

Files I am going to send to client are pretty big (cca 100MB each), so no way to compress them first then send the ZIP file to the browser and delete ZIP file after successfull download... There is also no way to create the ZIP file in memory due to the size of files... Only possiblity is to create a part of ZIP file (let say 1024KB) send it to client, create another part of ZIP file (1024KB) and so on and so on...

Is this possible with your component? Do you have an example on this?
