> Hi,
> I wanted to use this parameter to specify different solr configuration files for master and slave to simplify deployment procedure. Unfortunately, I can't dynamically replace the value of this parameter. Basically, what I want is
>   <filter>
>     <filter-name>SolrRequestFilter</filter-name>
>     <filter-class>org.apache.solr.servlet.SolrDispatchFilter</filter-class>
>     <init-param>
>       <param-name>solrconfig-filename</param-name>
>       <param-value>solrconfig-master.xml</param-value>
>     </init-param>
> </filter>
> for master instance, and
>   <filter>
>     <filter-name>SolrRequestFilter</filter-name>
>     <filter-class>org.apache.solr.servlet.SolrDispatchFilter</filter-class>
>     <init-param>
>       <param-name>solrconfig-filename</param-name>
>       <param-value>solrconfig-slave.xml</param-value>
>     </init-param>
> </filter>
> for slave instance.
> Ideally, if I can use system property for its value like in solrconfig.xml. For example,
>   <filter>
>     <filter-name>SolrRequestFilter</filter-name>
>     <filter-class>org.apache.solr.servlet.SolrDispatchFilter</filter-class>
>     <init-param>
>       <param-name>solrconfig-filename</param-name>
>       <param-value>${solr.config.filename: solrconfig.xml}</param-value>
>     </init-param>
> </filter>
> but I learned that in general we can't use system property in web.xml.
> I realize that I can use replication of config file to achieve this, but I thought that creates unnecessary dependencies for slaves on master instance.
> So here is my proposal:
> make SolrDispatchFilter look up another init parameter, say 'solrconfig-filename-property', and its value is a system property name, and if this property is set, we get the file name, otherwise nothing happens (of course, if both exist, 'solrconfig-filename' takes precedence). This will give us maximum flexibility of specifying configuration files for different instances.
> Your thoughts?
> Thanks,
> Jianhan
