Hi,

The file extension should be irrelevant unless you specify otherwise.
You should take a read of some of the VCL examples here:
https://www.varnish-cache.org/trac/wiki/VCLExamples.

Below is wholly untested sample code for explicitly caching .jsp files
for 1 hour.

--

sub vcl_recv {
# match .jsp files
if(req.url ~ "\.jsp$") {
return (lookup);
}
# [...]
}

sub vc_fetch {
if(req.url ~ "\.jsp$") {
# set ttl for one hour
set beresp.ttl = 1h;
}
# [...]
return (deliver);
}

Thanks,
Michael

You must make sure your JSP page allows Varnish to cache it, and/or
force caching in Varnish.

Keep in mind that cookie and set-cookie headers will usually make
Varnish not cache anything. If this is the case with your setup,
https://www.varnish-cache.org/trac/wiki/VCLExampleCacheCookies might be
helpful.

If you want a better response, you should show a varnishlog extract
where the .jsp page is not being cached (so we can see exactly *why*
it's not cached), and also your current VCL.

You are not considering set-cookie from the backend. This would be done
in vcl_fetch, as detailed in the URL I referred to in my previous response.

Also, as mentioned, please include a varnishlog extract.
