Jeff,
Thank you for the precisions, and for the updated documentation. Let
me make sure I understand this correctly.
The use case:
Simply put, when using Apache as a load balancer, I'd like to limit
the number of connections Apache makes to back-end servers. When
processing requests requires a f

Igor,
I am running Apache 2.2.14. Re-reading the documentation for "max", I see:
The default for a Hard Maximum for the number of connections is the
number of threads per process in the active MPM. In the Prefork MPM,
this is always 1, while with the Worker MPM it is controlled by the
ThreadsPerC
H I had to read the documentation again my self and I can't find any
mention of what type of MPM is supported in this case. All it says is
"Apache will never create more than the Hard Maximum connections to the
backend server" so it makes me expect that max parameter should be in force
no matte

I am using prefork MPM. Are you saying that since each request is
handled by one process, the max parameter doesn't work with prefork
MPM? Then how should I go about doing this (i.e. set

I am using the following Apache config to forward requests to a Tomcat server:
ProxyPass /myapp ajp://localhost:8009/myapp max=2
This is a simplified config, but is enough to reproduce the issue,
which is that the max parameter has no effect. If I through 10
concurrent requests to Apache, all
14 matches
