Peter Wolanin commented on SOLR-232:
------------------------------------
Looks like the title needs to change? From looking at the Solr 1.4 code, it
seems this issue is now about setting RESPONSE headers?
That's certainly the use case I have in mind, and what seems to be commented
out in the Solr 1.4 code:
https://svn.apache.org/repos/asf/lucene/solr/branches/branch-1.4/src/webapp/src/org/apache/solr/servlet/SolrDispatchFilter.java
{code}
// add info to http headers
//TODO: See SOLR-232 and SOLR-267.
/*try {
NamedList solrRspHeader = solrRsp.getResponseHeader();
for (int i=0; i<solrRspHeader.size(); i++) {
((javax.servlet.http.HttpServletResponse)
response).addHeader(("Solr-" + solrRspHeader.getName(i)),
String.valueOf(solrRspHeader.getVal(i)));
}
} catch (ClassCastException cce) {
log.log(Level.WARNING, "exception adding response header log
information", cce);
}*/
{code}
However, the things currently sent in the response header seem to be missing
the # of matches (logged as "hits"), and I'm not sure I'd want all the params
sent back as headers by default.
So, maybe we need a method like solrRsp.getHttpResponseHeader(); instead of
using solrRsp.getResponseHeader();
and corresponding setters?

>
> I need the ability to log certain information about a request so that I can
> feed it into performance and capacity monitoring systems.
> I would like to know things like
> - how long the request took
> - how many rows were fetched and returned
> - what handler was called.
> per request.
> the following patch is 1 way to implement this, I'm sure there are better
> ways.
