I am trying to develop a ASP.NET 2.0 commerce website. When the customer logs into the application we have to do a serious of operation(6 sequential webservice calls) and validate the offers the user is eligable to order thru the website. The webservice calls will take a minimum 30-45 seconds to complete the validations. Once the validation is done the user will be presented with the products that are eligible to order. During the validations are done, we don't want to show the user a blank page, instead we want to show them a progress animation and once the processing is done, the user should be taken to the order form.
I tried using HTML frames in my ASP.NEt page by having the progress animation shown in the top frame and loading another webpage (say page2.aspx) in the hidden bottom frame to do the webservice calls. This gives me success with the animation, but after the processing is complete when i do from the page2.aspx to show the order.aspx...i am facing issue. Since the page2.aspx is loaded in the bottom hidden frame, the order.aspx is loaded in the hidden frame and the user is struck there.
Please help me to solve this issue without making a round trip to the client browser and without compromising the application performance. Thanks in advance.
