> The reason for out of memory exception is that a FileItem object is created for 
> each request parameter whether it is file or an ordinary string parameter. the 
> FileItem object has a field of type DeferredFileStream which is initialized to 
> 262144 bytes (256 Kb) so if there are around 1000 request parameters, around 
> 256 MB of space will be required to hold the request parameters even though 
> most parameters may require only 8 to 10 bytes of memory for storage.
