SEP scan on server not client PC

Hi,

Since our environmet was built RemoteApp (Windows Explorer - explorer.exe) for file copy from different network (A to B to C)

Client (network A) must through RemoteApp on server (network B) to connect to laborary (network C).

Is possible to let SEP on server (network B) to scan the file that the client (network A) want to copy from laborary (network C) ??

Thanks
