Request Too Large

问题

I am receiving the following error on my page, I updated the IIS setting for posting limit, but can't find how to increase the work buffer size, any help on this would be awesome

Request Too Large
The "POST" request is too large for the internal work buffer:

    The internal work buffer size is 512 bytes.
    The "POST" request size is 2313 bytes. 

Return to last page

Official status error from firebug: 413 Request Entity Too Large

I am using IIS7.5 for setting up the page

The site is built via .NET MVC4

and I can not reduce the post size, in fact in some cases it only increase.
