Hi NG,

I tried to implement the compressionsink-example of Ingo Rammer.
the client-app.config-file looks like that
<channels>
<channel ref="http">
 <serverProviders>
  <provider ref="wsdl"/>
  <formatter ref="soap" typeFilterLevel="Full" />
  <formatter ref="binary" typeFilterLevel="Full" />
 </serverProviders>
 <clientProviders>
  <formatter ref="soap"/>
  <provider type="CompressionSink.CompressionClientSinkProvider,
CompressionSink" />
 </clientProviders>
</channel>
</channels>

the server-appp.config-file looks like that:
<channels>
<channel ref="http" port="1235">
 <serverProviders>
  <provider ref="wsdl"/>
   <formatter ref="soap" typeFilterLevel="Full" />
   <formatter ref="binary" typeFilterLevel="Full" />
  </serverProviders>
  <serverProviders>
   <provider type="CompressionSink.CompressionServerSinkProvider,
CompressionSink" />
   <formatter ref="soap"/>
  </serverProviders>
</channel>
</channels>

Without the clientProviders-part in the client-app.config-file the example
works fine and the serverside CompressionSink.dll is used.
But with this part the app gets the Exception
System.Xml.XmlException: Ung?ltiges Zeichen in der angegebenen Codierung.

now my CallPoint.

I use the .Net Framework 1.1.
Where the bug, or is there a better way in .Net 1.1 to reduce the network
traffik.

Thanks a lot
