That may be a little problem in coding the things.
How are you specifying the end of file transfer to the client. If the client doen't know the completion of transfer it blocks the way. If you want to make this synchronous then using the proper threading mechanism you can do this.

Otherwise follow your own protocol to specify the file size and let the client know the trnasfer complete.

This may help you in reaching the goal...if not feel free to contact me at
