Systems, methods, and computer-readable media for securing a mobile device application using an application wrapper while preserving and/or improving performance of the wrapped application are presented. In one or more embodiments, an application wrapper may detect, during execution of a wrapped application, at least one performance caused by the application wrapper. The application wrapper may modify execution of the wrapped application to address the at least one detected performance issue. In some instances, the at least one performance issue may be associated with a cache that stores one or more pages from a database, and the cache and the database may be maintained within the wrapped application.

Performance of a wrapped application

A mechanism for remoting Twain function calls within a user session to a client system is disclosed. By hooking Twain function calls made by a Twain application on the server, the Twain function calls may be remoted over a virtual connection to a client system. A proxy application corresponding to the server-based Twain application is created on the client system. The proxy application communicates with the server and makes the appropriate function calls to the remainder of the Twain framework. The use of the proxy application allows multiple applications and devices to be supported simultaneously. Messages sent over the virtual connection are filtered prior to transmission thereby limiting the amount of required communication traffic. A multiplexor and demultiplexor are utilized in order to efficiently use bandwidth on the virtual channel. The present invention additionally compresses image data prior to transmission over the virtual channel.

The present invention relates to a method and apparatus for managing and balancing the load of each of the servers in the network. In one aspect, the invention relates to an apparatus for managing server load in a networked system of servers. The apparatus includes a dynamic store storing run-time information associated with a plurality of servers in a server farm. The apparatus also includes an event bus. The apparatus also includes a load management subsystem in communication with the dynamic store via the event bus. The load management subsystem receives a request from the event bus to identify a server and transmits a message to the event bus that includes an address of an identified server based on information from the dynamic store.
