Hey Tomcat developers,
Does AJP13 behave similarly to HTTP 1.1 in terms of socket keep-alive? Does
Apache/mod_jk(2) maintain a pool of persistent connections to the Tomcat server or are
the connections transient? My exploration with netstat indicates that the connections
are persistent which holds consistent with common practices for TCP efficiency. If
this is the case how are these persistent connections allocated to incoming HTTP
requests? I've seen 50-60 ESTABLISHED connections between my Apache 2.0.45 and each
of two Tomcat 4.1.24 instances (so 100-120 total ESTABLISHED AJP connections) even
though I know that my number of concurrent user HTTP requests is much smaller than
that at 30 or so. If the pool of consistent connections were being used as expected I
would expect to see only 30 or so (maybe up to 50-60 for spikes) AJP connections or
about 15-30 per Tomcat. Any thoughts?
Many thanks!
