That is not problem of IIS but the problem of WCF. WCF by default limits messages to 65KB to avoid denial of service attack with large messages. Also if you don't use MTOM it sends byte[] to base64 encoded string (33% increase in size) => 48KB * 1,33 = 64KB

To solve this issue you must reconfigure your service to accept larger messages. This issue previously fired 400 Bad Request error but in newer version WCF started to use 413 which is correct status code for this type of error.

You need to set <code>maxReceivedMessageSize</code> in your binding. You can also need to set <code>readerQuotas</code>.

<pre><code>&lt;system.serviceModel&gt;
 &lt;bindings&gt;
 &lt;basicHttpBinding&gt;
 &lt;binding maxReceivedMessageSize="10485760"&gt;
 &lt;readerQuotas ... /&gt;
 &lt;/binding&gt;
 &lt;/basicHttpBinding&gt;
 &lt;/bindings&gt; 
&lt;/system.serviceModel&gt;
</code></pre>

I was having the same issue with IIS 7.5 with a WCF REST Service. Trying to upload via POST any file above 65k and it would return Error 413 "Request Entity too large".

The first thing you need to understand is what kind of binding you've configured in the web.config. Here's a great article...

<a href="https://stackoverflow.com/questions/2650785/basichttpbinding-vs-wshttpbinding-vs-webhttpbinding">BasicHttpBinding vs WsHttpBinding vs WebHttpBinding</a>

If you have a REST service then you need to configure it as "webHttpBinding". Here's the fix:

<pre><code>&lt;system.serviceModel&gt;

&lt;bindings&gt;
 &lt;webHttpBinding&gt;
 &lt;binding 
 maxBufferPoolSize="2147483647" 
 maxReceivedMessageSize="2147483647" 
 maxBufferSize="2147483647" transferMode="Streamed"&gt;
 &lt;/binding&gt; 
 &lt;/webHttpBinding&gt;
&lt;/bindings&gt;
</code></pre>

For anyone else ever looking for an IIS WCF error 413 : Request entity to large and using a WCF service in Sharepoint, this is the information for you. The settings in the application host and web.config suggested in other sites/posts don't work in SharePoint if using the MultipleBaseAddressBasicHttpBindingServiceHostFactory. You can use SP Powershell to get the SPWebService.Content service, create a new SPWcvSettings object and update the settings as above for your service (they won't exist). Remember to just use the name of the service (e.g. [yourservice.svc]) when creating and adding the settings. See this site for more info <a href="https://robertsep.wordpress.com/2010/12/21/set-maximum-upload-filesize-sharepoint-wcf-service" rel="nofollow">https://robertsep.wordpress.com/2010/12/21/set-maximum-upload-filesize-sharepoint-wcf-service</a>

blocks|key|597610|text|在我的例子中，我必须增加BizTalk中接收位置的“最大接收消息大小”。它的默认值也是64K，因此无论我在web.config中配置了什么，BizTAlk都会将每封邮件退回|type|unstyled|depth|inlineStyleRanges|entityRanges|data|597611|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

In my case I had to increase the "Maximum received message size" of the Receive Location in BizTalk. That also has a default value of 64K and so every message was bounced by BizTAlk regardless of what I configured in my web.config

blocks|key|597666|text|我已经能够通过在同一个wcf通道/客户端上的请求之前执行一个虚拟调用(例如，IsAlive返回true+)来解决这个问题。显然，ssl协商是在第一次调用时完成的。所以不需要增加Uploadreadaheadsize。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|597667|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I've been able to solve this by executing a dummy call ( e.g. IsAlive returning true ) just before the request with large content on the same wcf channel/client. Apparently ssl negotation is done on the first call. So no need to increase Uploadreadaheadsize.

blocks|key|597739|text|对我来说，在增加了对uploadReadAheadSize绑定的限制后，将int.MaxValue设置为WCF也解决了这个问题。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|597740|看起来，在使用SSL时，整个请求实体主体都是预加载的，为此使用了此元数据库属性。|597741|有关详细信息，请参阅：|597742|The+page+was+not+displayed+because+the+request+entity+is+too+large.+iis7|597743|entityMap|0|LINK|mutability|MUTABLE|url|https://stackoverflow.com/questions/22762311/the-page-was-not-displayed-because-the-request-entity-is-too-large-iis7^0|A|J|0|0|0|0|20|0|0^^$0|@$1|2|3|4|5|6|7|T|8|@$9|U|A|V|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|W|8|@]|D|@]|E|$]]|$1|H|3|I|5|6|7|X|8|@]|D|@]|E|$]]|$1|J|3|K|5|6|7|Y|8|@]|D|@$9|Z|A|10|1|11]]|E|$]]|$1|L|3|-4|5|6|7|12|8|@]|D|@]|E|$]]]|M|$N|$5|O|P|Q|E|$R|S]]]]

For me, setting the <code>uploadReadAheadSize</code> to int.MaxValue also fixed the problem, after also increasing the limits on the WCF binding.

It seems that, when using SSL, the entire request entity body is preloaded, for which this metabase property is used.

 &lt;/system.webServer&gt;
 &lt;/location&gt;
&lt;/configuration&gt;

I've written a WCF service with .NET 4.0, which is hosted on my Windows 7 <code>x64</code> Ultimate system with IIS 7.5.
One of the service methods has an 'object' as argument and I'm trying to send a byte[] which contains a picture.
As long as the file size of this picture is less then approx. 48KB, all goes well. But if I'm trying to upload a larger picture, the WCF service returns an error: <code>(413) Request Entity Too Large.</code>
So ofcourse I've spent 3 hours Googling the error message and every topic I've seen about this subject suggests raising the 'uploadReadAheadSize' property.
So what I've done is using the following commands (10485760 = 10MB):

<code>"appcmd.exe set config -section:system.webserver/serverruntime/uploadreadaheadsize: 10485760 /commit:apphost"</code>

<code>"cscript adsutil.vbs set w3svc/&lt;APP_ID&gt;/uploadreadaheadsize 10485760"</code>

I've also used IIS Manager to set the value by opening the site and going to "Configuration Editor" under Management.
Unfortunately I'm still getting the Request Entity Too Large error and it's getting really frustrating!

So does anybody know what else I can try to fix this error?
