setPathPrefix

public void setPathPrefix(java.lang.String pathPrefix)

Set the prefix for all paths. This is useful if you want to apply the filter to something other then /*, perhaps because you are merging this filter into a larger web application. For example, if web.xml specifies: SolrRequestFilter /xxx/* Make sure to set the PathPrefix to "/xxx" either with this function or in web.xml. path-prefix /xxx

getPathPrefix

public java.lang.String getPathPrefix()
