http handler problem

[Evgeny Lavrinenko]

Hello everyone.

I want to implement http handler but when  I change settings in config.xml from the example:

<http_handlers>

    <rule>

        <url><![CDATA[/query_param_with_url/\w+/(?P<name_1>[^/]+)(/(?P<name_2>[^/]+))?]]></url>

        <method>GET</method>

        <headers>

            <XXX>TEST_HEADER_VALUE</XXX>

            <PARAMS_XXX><![CDATA[(?P<name_1>[^/]+)(/(?P<name_2>[^/]+))?]]></PARAMS_XXX>

        </headers>

        <handler>

            <type>predefined_query_handler</type>

            <query>SELECT value FROM system.settings WHERE name = {name_1:String}</query>

            <query>SELECT name, value FROM system.settings WHERE name = {name_2:String}</query>

        </handler>

    </rule>

</http_handlers>

then server stops to respond: Code: 210. DB::NetException: Connection refused (localhost:9000)

I thought I could be an issue of wrong version of clickhouse, so I updated server to the latst release but I am still getting the same behaviour.

Can anyone help me with this issue, please?
