Given an apache 2.4 server with:
ReadRequestTimeout header=60-65,rate=500
When a client opens a persistent connection to that server, does the
request timeout apply to
a) each request sent down the connection individually, or
b) the whole connection, i.e. the connection will close after 65
seconds of reading requests even if there
are more requests ready to send
Background:
I have two apache 2.4 servers, one acting as a reverse proxy for the
other. Both have mod_reqtimeout enabled.
The reverse proxy is using persistent connections to talk to the backend.
I have applied a steady test load of 1 request per second; requests are
quick to process in the backend
I'm getting 502 errors from the front end. It appears that the backend
is closing the connections, though its hard to be sure which end is.
The rate of 502 errors reduces the longer I make the
ReadRequestTimeout. I get no errors if I disable mod_reqtimeout. It
looks like the backend is closing then connections after about N seconds
where N is the timeout value, even in the presence of a steady load.
MaxKeepAliveRequests and KeepAliveTimeout are set very high.
I'm pretty new to this sort of thing. I'd appreciate any thoughts or
guidance.
