Question

I have a application developed in asp net mvc 4 (IIS 7 and windows server 2008) and it has a upload system.

The problem is that with large files I get an 413 http error.

I am trying to set uploadaheadsize but can´t find it anywhere.

Tried Roles and features and also in application pool. Could someone guide me through this config setting?
Thanks.

Answer 1

I found the solution.

Just added:

<security>
  <requestFiltering>
    <requestLimits maxAllowedContentLength="524288000"/>
  </requestFiltering>
</security>

in my web.config!

Edit 1:

In addition, I found this useful information on http://www.iis.net:

The requestLimits element specifies limits on HTTP requests that are
processed by the Web server. These limits include the maximum size of
a request, the maximum URL length, and the maximum length for a query
string. In addition, the element can contain a
collection of user-defined HTTP header limits in the
element, which allows you to define custom settings on HTTP headers.
