Solr httpCaching for distinct handlers

[mat0112 <el...@outlook.com>]

Hi everybody, I would like to have distinct httpCaching configuration for
distinct handlers, i.e if a request comes for select, send a cache control
header of 1 minute ; and if receive a request for mlt then send a cache
control header of 5 minutes.
Is there a way to do that in my solrconfig.xml ?
Thanks!

Unfortunatenly no.

the request handlers are agnostic to the fact that they run in a servlet 
container, only the requestDispatcher has settings related to the caching 
headers.

Two options you could consider depending on your end goal...

1) put a proxy in front of Solr that specifies the Cache-Control header 
based on pattern matching of the URL.  (There may be an existing servlet 
filter you could configure in jetty for this)

2) if you already have a caching proxy in front of Solr, and your goal is 
to changing how long that proxy caches the responses, you might be able to 
configure it explicitly assume certain max-ages based on the request URL 
(this is a very nice feature of Squid for example)
