A:
 

You can use PDFTron WebViewer for the task. To find out more info about WebViewer please see: http://www.pdftron.com/pdfnet/webviewer/index.html and see a demo of the form-filling capabilities here: http://www.pdftron.com/pdfnet/webviewer/demo/samples.html. 
 
Basically, the system would work like this:

1. Server component based on PDFNet converts source PDF to XOD, an XPS-compatible format.
2. Browser-based WebViewer component renders the XOD file (including fillable forms).
3. WebViewer sends filled form data back to the PDFNet server component.
4. PDFNet server component makes a new copy of the original PDF with new form data entered by the user.
5. Browser can download PDF with filled forms.
