HTTP/1.1 413 Request Entity Too Large

Question

Hi Team,

I have exposed my schema as a Service using the WCF Publishinf wizard the binding I have used is WCF Basic HTTP.

Since we are Testing one of our solution with a large file(100 MB) I have increased my Time Out Values and the MaxReceive message zize to 1048576 on my Receive Location.

From the client also I have Updated by binding value to

maxBufferPoolSize

="2147483647"maxBufferSize="2147483647"maxReceivedMessageSize="2147483647"

in the app config file

but still at the client I get the Error saying the Request Entity is too large.

Can you Please help me with this?

Thanks,

sujith.

Hi Sujith,

Refer the article: https://blogs.msdn.microsoft.com/dsnotes/2015/08/21/large-file-upload-failure-for-web-application-calling-wcf-service-413-request-entity-too-large/

You should consider configuring WCF verbose level tracing for the service and client. For more information on configuring WCF tracing please see the link – https://msdn.microsoft.com/en-us/library/ms733025%28v=vs.110%29.aspx

Check the IIS request Filtering and set the Maximum allowed content length to higher value. Also there is a setting present in the IIS – “UploadReadAheadSize” that prevents upload and download of data greater than 49KB.The value present by default is 49152 bytes and can be increased up to 4 GB.

You can refer an old thread: Cannot consume WCF service. (413) Request Entity Too Large
Try removing named binding configuration and use the default one.

Another that what is mentioned in the article you should also consider setting httpRuntime Element- maxRequestLength with appropriate value in your web.config.

Refer discussion here.
