Zoho Writer Submit Problem

Zoho Writer Submit Problem

Hi all,
 
I started using Zoho lately and I faced a problem in Writer.
 
I open a doc file with Writer, everything seems to be OK. However when I save the file I get the following error:
 
"Problem in posting the document. Please retain a local copy at your end and try again later."
 
On the other hand I open an excel sheet and I give the same saveurl. Here I got no problem and the document is saved successfully.
 
Can anyone explain to me what I am doing wrong?
 
Here is my asp.net code for saving files coming from Zoho server:
 

string

 path = Request.Form[ "id" ]; //I save the file path in id

HttpPostedFile file = Request.Files[

 "content" ];

 if (file != null )

{

      file.SaveAs(Server.MapPath(path));

      Response.Write(

 "RESPONSE:File saved successfullyy" );

}
 
This is code is never run by writer, but run with sheet.
 
Thanks in advance
