Abstract: A remote request system and method monitors and controls the execution of remote requests on an on-line services network. When a remotely located client sends a remote request to the on-line service network, the remote request system monitors the remote request while returning operating control back to the client while the remote request remains pending in the on-line service network. The remote request system also provides for the concurrent execution of multiple pending remote requests, provides status information about each remote request, provides for the cancellation of a pending remote request and optimizes the use of memory. In addition, the remote request system dynamically allocates memory when data blocks of unknown size are transmitted over the on-line services network.
