Consider the following scenario. You have a web site that is hosted on a server that is running IIS 7.0. When a user visits this web site, the user receives an error message that resembles the following error message:
Server Error in Application "application name"
HTTP Error 404.13 - CONTENT_LENGTH_TOO_LARGE
Description of HRESULT # The operation completed successfully.
This problem occurs because the client request contains a
Content-Length header that is larger than the value that is specified for this header in the
maxAllowedContentLength property in the ApplicationHost.config file.
To resolve this problem, follow these steps:
Select Start. In the Start Search box, type Notepad. Right-click Notepad, and then select Run as administrator.
If you are prompted for an administrator password or for a confirmation, type the password, or select Continue.
On the File menu, select Open. In the File name box, type
%windir%\system32\inetsrv\config\applicationhost.config, and then select Open.
In the ApplicationHost.config file, locate the
maxAllowedContentLengthproperty. Or, add a value that matches the size of the
Content-Lengthheader that the client sends as part of the request. By default, the value of the
maxAllowedContentLengthproperty is 30000000.
For example, modify the following configuration data inside the
<requestLimits maxAllowedContentLength ="<length>" />
Save the ApplicationHost.config file.
