Isn't Filter.doFilter() called once for each incoming http request?
Yes, which is why it has nothing to do with the number of _connections_.
To elaborate just a little :
Presumably when the OP wrote "connections", he meant "connections",
and this was not just sloppy language.
In that case, consider "keep-alive" connections : a browser
establishes *one* connection to Tomcat, and then uses that same
connection to send 100 HTTP requests (and get 100 HTTP responses) over
that same connection.
A filter would count 100 requests (assuming that they are all to that
same application), but there would still be a single connection.
(On the other hand of course, if all the request were directed to
another application which does not have the filter, then the filter
would count 0 requests, and there would still be 1 connection).
Talking about fuzzy language though, review Mark's original response :
which "connections" are we talking about here ? and are we talking
about a "snapshot", where we want to know how many connections with
Tomcat are active at a specific moment in time, or how many
connections with Tomcat have been established/closed over a period of
time ?
Or about something else altogether ?
And if one really wanted to count connections at the Tomcat level, I
would imagine that the sensible place to do this would be at the
Connector level, no ? (all of them)
