Remoting Config File Question - SOAP and Binary

I have a config file with remoting information as noted below. The remoting calls can come back in either soap or binary format. I have read the MSDN articles on this, but am having a hard time understanding why the config file has to be the same on both sides. Can someone explain this The server side is the remoted side and the client side is my "web" project side, yes Why is the typeFilterLevel required in server only The articles I have found are difficult to understand for a beginner in remoting jargon. Your help is appreciated!!!

Config in the web project:

<channels>

<channel ref="http">

<serverProviders>

<provider ref="wsdl" />

<formatter ref="soap" typeFilterLevel="Full" />

<formatter ref="binary" typeFilterLevel="Full" />

</serverProviders>

<clientProviders>

<formatter ref="binary" />

</clientProviders>

</channel>

</channels>
