Hi Sarathlal,
I followed your multipart code for uploading larger files. Its working for me in localhost, but in IIS, i could not upload more than 29 MB file.
I googled and followed all the suggesstions such as:
increased maxAllowedContentLength in RequestFiltering
Added the below line in web.config
<serverRuntime uploadReadAheadSize="10485760" maxRequestEntityAllowed="52428800" />
But still, I could not upload file which is greater than 30 MB.
Kindly suggest anything...
