Well, Actually I showed how to do this.
Did you read the article I specified. I think you need to modify the Machine.config as it will always override the value with this one.
Normal files in asp.net defaults to 4,096 kilobytes(4MB), if you need larger than this, go to
\System Root\Microsoft.NET\Framework\Version Number\Config
folder and change
To the value you need. I dont think changing to web.config works.
I hope this will solve the issue. :thumbsup:
