Setting up gzip compression to optimize text throughtput

Question

Hello,
I struggled to setup my dev cluster with gzip but it's running okay. However I cannot connect to it from .Net client. The server complains with Not in GZIP format
What do I miss?
Thanks,
Michal
BTW: The for doc .Net is not very great (since when one put's documentation in a dtd file?!? see [Network Filters |http://coherence.oracle.com/display/COH35UG/Network+Filters#]... ).
On client I have
app.config
<coherence>
<coherence-config>Config\coherence.xml</coherence-config>
<cache-config>Config\cache-config.xml</cache-config>
<pof-config>Config\pof-config.xml</pof-config>

Answer 1

in .Net I have app.config file which specifies which .xml files are used. At least that's how the Coherence.Net example is configured. Basically I would like to know the schema for Config\coherence.xml referenced in app.config.
As the documentation http://download.oracle.com/docs/cd/E15357_01/coh.360/e15726/net_netfilters.htm#sthref213 states:
|"There are two steps to configuring a filter." The first is to declare the filter in the <filters> XML element of the cache |factory configuration file. This is illustrated in Example 23-2:
|
|Example 23-2 Configuring a Filter
|
|<coherence>
| <cluster-config>
| <filters>
| <filter>
| <filter-name>gzip</filter-name>
| <filter-class>Tangosol.Net.CompressionFilter, Coherence</filter-class>
| </filter>
| </filters>
| </cluster-config>
|...
|</coherence>
1) It is really unclear whether it should be done on client or on the proxy!!! 2) Just pasting this into coherence.xml does not work with client complaining on "Could not find schema information for the element 'coherence'" This example is clearly wrong by not specifying the name of XML schema...
|The second step is to attach the filter to one or more specific services. To specify the filter for a specific service, for |example the ExtendTcpCacheService service, add a <filter-name> element to the <use-filters> element of the service |declaration in the cache configuration file.
|
|Example 23-3 Attaching a Filter to a Service
|
|<remote-cache-scheme>
| <scheme-name>extend-direct</scheme-name>
| <service-name>ExtendTcpCacheService</service-name>
| <initiator-config>
| ...
| <use-filters>
| <filter-name>gzip</filter-name>
| </use-filters>
|
| ...
|</remote-cache-scheme>
I am pretty sure it's on the client as that's where my <tcp-initiator> and then <address> of my cluster proxy is. theoretically these "two steps" should be easy...
