I currently have a WCF service with webHttp bindings, im attempting to increase the max size that can be inputted to the service by overriding the default settings in config, i have tried doing something like
<system.serviceModel>
<bindings>
<webHttpBinding>
<binding name="webHttp" >
<security mode="Transport">
<transport clientCredentialType =
"None"
proxyCredentialType="None"
realm="string" />
</security>
</binding>
</webHttpBinding>
</bindings>
<services>
<service name="PrimeStreamInfoServices.Service1" behaviorConfiguration="PrimeStreamInfoServices.Service1Behavior">
<!-- Service Endpoints -->
<endpoint address="" binding="webHttpBinding" contract="PrimeStreamInfoServices.IService1">
<!--
Upon deployment, the following identity element should be removed or replaced to reflect the
identity under which the deployed service runs. If removed, WCF will infer an appropriate identity
automatically.
-->
</endpoint>
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="PrimeStreamInfoServices.Service1Behavior">
<!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
<serviceMetadata httpGetEnabled="true"/>
<!-- To receive exception details in faults for debugging purposes, set the value below to true. Set to false before deployment to avoid disclosing exception information -->
<serviceDebug includeExceptionDetailInFaults="false"/>
</behavior>
</serviceBehaviors>
</behaviors>
<diagnostics>
and setting various other properties pertaining to message size but none seems to be working, can one even change the m essage size of a webHttp binding? Any suggestions? Thanks!
There's a multitude of settings that might have an influence depending on your settings - try this:
<bindings>
<webHttpBinding>
<binding name="LargeWeb"
maxBufferPoolSize="1500000"
maxReceivedMessageSize="1500000"
maxBufferSize="1500000">
<readerQuotas
maxArrayLength="656000"
maxBytesPerRead="656000"
maxDepth="32"
maxNameTableCharCount="656000"
maxStringContentLength="656000"
/>
</binding>
</webHttpBinding>
</bindings>
By defining your "version" of the webHttpBinding and setting all those parameters to higher values, you should be able to get through any message size (almost).
Mind you: this does open up your system to the potential of being flooded with huge messages and thus be brought down to its knees (classic denial-of-service attacks) - that's the reason these limits are set fairly low - by design and on purpose.
You can change them to higher values - just be aware what you're doing and what the security risks are, if you do!

PS: In order to make use of these settings, you of course have to reference that binding configuration in your server and client side configs:
<client>
<endpoint address="http://localhost"
binding="webHttpBinding" bindingConfiguration="LargeWeb"
contract="IMyService" />
</client>
<services>
<service>
<endpoint address="http://localhost"
binding="webHttpBinding" bindingConfiguration="LargeWeb"
contract="IMyService" />
</service>
</services>
