(413) Request Entity Too Large

Hi guys.

I`m making a simple uploading app in my system,

but when I'm trying to upload image size more than 50kb "remote server returned an unexpected response (413) request entity too large" error always come up.

googled and seeing other post on this forum and done these things below but nothing worked.

1.setting MaxReceivedMessage

2.setting uploadReadAheadSize

3. set serverRuntime overrideModeDefault into allow in applicationHost.config

I'm using IIS 6 with .netFramework 4.0

and this is my app web.congfig
