I am getting this error while sending files data as base64 string through headers

HTTP Error 400. The size of the request headers is too long.

even I have done some settings in the web.config for receiving large data as follows:

C#

<system.servicemodel>
        <bindings>
            <webhttpbinding>
                <binding name="SecureBinding" maxreceivedmessagesize="2147483647" maxbuffersize="2147483647" transfermode="Buffered">

                    <security mode="Transport">

                            <extendedprotectionpolicy policyenforcement="Never" />
                        </transport>
                    </security>
                </binding>
            </webhttpbinding>
        </bindings>

        <services>
            <service behaviorconfiguration="WCFService.Service1Behavior">

I would make sure you have endpoint behaviour configurations in the client and server with the maxItemsInObjectGraph property set

XML

<endpointbehaviors>
        <behavior name="endpointBehavior">
          <datacontractserializer maxitemsinobjectgraph="2147483647" />
        </behavior>
      </endpointbehaviors>

Make sure each endpoint binding uses this behaviour like:

XML

<endpoint behaviorconfiguration="endpointBehavior" ....=""></endpoint>

secondly I would check your client http request rate:

XML

<httpruntime executiontimeout="90" maxrequestlength="20000" usefullyqualifiedredirecturl="false" requestlengthdiskthreshold="8192" />
