Design Proposal for a Date/Time triggered HTTP request service

I require a design proposal for a robust service/application that will perform HTTP GET/POST requests to web pages at specific times. Please refer to the attachment for more details. To be successful you need to be able to demonstrate:- 1. A strong knowledge in writing technical specifications 2. A strong knowledge technical understanding. ## Deliverables 1) Complete desgin specification for the above project. 2) All deliverables will be considered "work made for hire" under U.S. Copyright law. Buyer will receive exclusive and complete copyrights to all work purchased. (No GPL, GNU, 3rd party components, etc. unless all copyright ramifications are explained AND AGREED TO by the buyer on the site per the coder's Seller Legal Agreement). ## Platform Open to suggestions in the deliverable design document. I would expect either Linux/Java/MySQL or Windows/C#/SQL Server. Certainly an Object-Orientated language.
