The request is too big

Question

I get the following error on my page, I updated the IIS parameter to limit sending, but cannot find how to increase the size of the working buffer, any help on this would be amazing

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 firebug status error: 413 Request entity too large

I use IIS7.5 to configure the page

Site built through .NET MVC4

and I can’t reduce the size of the message, because in some cases it only increases.
