Efficient fault tolerance technique for controlling the user session flow over online transaction applications

Users use the web for accessing all type of real time information. The user generates the request with required parameters that are verified at the remote end thereby allowing access to all type of resources. Such resources are extracted from more than one page. A user's interaction over a web page will differ from another with respect to the access level. The users may be classified based on the access level as basic, normal and advanced. A user committing a fault in an online transaction may face problems in successfully completing the transaction. The user session is maintained based on the access level with fault tolerance technique. The flow of the session is allotted based on the user access level only. The basic user cannot continue the session flow further, upon committing a fault, because this type of user never completes the transaction successfully. The normal user continues the session until he reaches the threshold level where as the advanced user always get a proper session flow to complete his online transaction. The main objective of the proposed work is to control the session flow based on the user access level in conjunction with fault committed by them. The session flow is properly assigned to the user who actually completes the online transaction with necessary information in a successful manner.
