Abstract: In some embodiments, a web-based postage transaction may be facilitated. In some embodiments, an applet embedded on a web page may be provided to a client computer in response to the client computer accessing the web page. A request related to a postage transaction may be received from the client computer. In response to the request, a validation check may be performed by providing a validation token to the embedded applet at the client computer to be validated by the embedded applet. Based on a determination by the embedded applet at the client computer that the validation token is valid, the embedded applet at the client computer is configured to execute at least a part of the request.

Abstract: A system and method for conducting a web-based postage transaction, includes receiving user credentials at a web server, validating the user credentials, and in response to valid credentials, providing access to a remote client to at least one module of a postage software application. The module is configured to execute requests to perform the web-based postage transaction and to, for each revenue generating request, perform a validation check. The validation check includes a requirement that the module have access to the web server for the request to be fulfilled. In an embodiment, the postage software application includes a module configured and arranged to determine the availability of a client-side device configured to execute the request to perform the web-based postage transaction and, when the client-side device is unavailable, to prevent execution of the request, and when the client-side device is available, to allow execution of the request.
