http/1.1 413 request entity too large

Dears,

I am creating a wcf service in which i am uploading two pdf files.

When i upload one file, it is working fine but if i do it for two files, it is giving me the error http/1.1 413 request entity too large in soapui.

Tried different options still i am unable to rectify the issue.

Following is my web.config details

<bindings>

<basicHttpBinding>

<binding name="A2" maxBufferPoolSize="2147483647"  maxBufferSize="2147483647" maxReceivedMessageSize="2147483647">     <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647"maxArrayLength="2147483647"               maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />

<security mode="Transport">

<transport clientCredentialType="Certificate" />

</security>

</binding>

</basicHttpBinding>

</bindings>

<client>

<endpoint address="https://Service" binding="basicHttpBinding"  bindingConfiguration="A2" contract="AS.Aspt"name="A2name" />

</client>

added the below in applicationHost also , still it is not working.

<serverRuntime uploadReadAheadSize="2147483647" />

<section name="serverRuntime" overrideModeDefault="Allow" />

set the uploadReadAheadSize in iis to 2147483647

Thanks

Nick
