                Hi,
                 
                I  have developed an application in ASP.NET and hosted 
                on Brinksters.
                I have framework 1.1
                I  have 2  issues
                 
                Issue 1 - Page refresh
                Issue 2 - Invalid PInvoke metadata format. 
                 
                 
                Issue 1) Page Refresh
                 
                I have a form for customers. If I accesss the page, it 
                displays the page with the previously accessed values. 
                Surprisingly this works perfectly fine when I run on a local 
                host.
                 
                Below is the code of customer aspx and web.config
                 
                Appreciate your help on this.
