Edit PDF on the Internet and save and generate data on the server

I have some PDF documents that are displayed in a browser, and some fields are already populated from the database using iTextSharp (we are running Windows Server 2008, IIS 7, SQL Server 2008 and ASP.NET 2.0 / 2.5 with C #) . Our customers should be able to fill out the remaining fields and save the PDF file on the server.

I reviewed the following options:

1.) Somehow using iTextSharp to analyze the form fields, take all the form data and save it in the database to submit.

2.) Adding the submit button to the PDF itself using LiveCycle with some JS click event to save the FDF / XFDF / XDP / XML data either to the database or to a flat file on the server.

I'm currently not sure about what the best approach will be, what will work, or how to implement any of these possible solutions, so any help would be greatly appreciated.

Update:

We managed to send the data in PDF format back to the server, convert FDF to XML and save it to the database. However, LiveCycle dynamic PDF files do not work the same. When we send the PDF back to the server, we get a 500 Internal Server Error. Thus, the process still works, but only on our static (not LiveCycle) PDF files.

Any idea why we can get an internal server error in LiveCycle forms?
